CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation application of U.S. patent application Ser. No. 17/024,226, filed on Sep. 17, 2020, which is a continuation application of U.S. patent application Ser. No. 15/273,969, filed on Sep. 23, 2016, which claims priority to U.S. Provisional Patent Application No. 62/348,971, filed on Jun. 12, 2016, which are hereby incorporated by reference in their entirety. 
    
    
     TECHNICAL FIELD 
     This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces that enable playback of media items. 
     BACKGROUND 
     The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Example touch-sensitive surfaces include touchpads and touch-screen displays. Such surfaces are widely used to manipulate user interface objects on a display. 
     Example manipulations include adjusting the position and/or size of one or more user interface objects or activating buttons or opening files/applications represented by user interface objects, as well as associating metadata with one or more user interface objects or otherwise manipulating user interfaces. Example user interface objects include digital images, video, text, icons, control elements such as buttons and other graphics. A user will, in some circumstances, need to perform such manipulations on user interface objects in a file management program (e.g., Finder from Apple Inc. of Cupertino, California), an image management application (e.g., Aperture, iPhoto, Photos from Apple Inc. of Cupertino, California), a digital content (e.g., videos and music) management application (e.g., iTunes from Apple Inc. of Cupertino, California), a drawing application, a presentation application (e.g., Keynote from Apple Inc. of Cupertino, California), a word processing application (e.g., Pages from Apple Inc. of Cupertino, California), a website creation application (e.g., iWeb from Apple Inc. of Cupertino, California), a disk authoring application (e.g., iDVD from Apple Inc. of Cupertino, California), or a spreadsheet application (e.g., Numbers from Apple Inc. of Cupertino, California). 
     But methods for performing these manipulations are cumbersome and inefficient. For example, using a sequence of mouse-based inputs to select one or more user interface objects and perform one or more actions on the selected user interface objects is tedious and creates a significant cognitive burden on a user. In addition, these methods take longer than necessary, thereby wasting energy. This latter consideration is particularly important in battery-operated devices. 
     SUMMARY 
     Accordingly, there is a need for electronic devices with faster, more efficient methods and interfaces for playing back media items. Such methods and interfaces optionally complement or replace conventional methods for playing back media items. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges. 
     The above deficiencies and other problems associated with user interfaces for electronic devices with touch-sensitive surfaces are reduced or eliminated by the disclosed devices.

In some embodiments, the user interacts with the GUI primarily through stylus and/or finger contacts and gestures on the touch-sensitive surface. In some embodiments, the functions optionally include image editing, drawing, presenting, word processing, website creating, disk authoring, spreadsheet making, game playing, telephoning, video conferencing, e-mailing, instant messaging, workout support, digital photographing, digital videoing, web browsing, digital music playing, and/or digital video playing. Executable instructions for performing these functions are, optionally, included in a non-transitory computer readable storage medium or other computer program product configured for execution by one or more processors.

     DESCRIPTION OF EMBODIMENTS 
     Many electronic devices have graphical user interfaces for playing back media items. In some such media player user interfaces, an image associated with a media item being played back is displayed in conjunction with playback of the media item. For example, while playing a song (e.g., through a speaker), album art associated with an album of the song is displayed (e.g., on a display). When the image is displayed on a touch-sensitive surface, the display region of the image occupies display space that could be otherwise occupied by interaction affordances allowing a user to change playback of media items. Accordingly, in embodiments described below, the image itself is configured as an interaction affordance that allows a user to change playback of media items. For example, in response to detecting a touch on the image, the device pauses or plays the media item. As another example, in response to a swipe over the image, the device plays a different media item. 
     While playing a media item, a user can desire to play other media items without interrupting playback of the current media item. Thus, many electronic devices include affordances for adding media items to a queue. However, in some cases, a user can desire to play other media items without interrupting playback of a predefined group of media items to which the media item belongs (e.g., an album of a song or a playlist including the song). Accordingly, in embodiments described below, options are provided for adding media items to queue to be played after not just the currently playing media item, but after a predefined group of media items to which the media item belongs. 
     Users may enjoy consuming a large number of media items. However, a large number of media items stored on an electronic device can use a large amount of storage, preventing other storage operations, such as storage of applications. Some electronic devices can delete media items stored by the electronic device in order to free storage for other storage operations. In some cases, this may result in an undesirably low amount of media items stored on the electronic device. Accordingly, in embodiments described below, a user is provided with an option to reserve an amount of storage of the electronic device for media items. The electronic device is allowed to delete media items in order to perform other storage operations, but must maintain at least a threshold amount of media items in storage. 
     The creation of media item playlists can be an arduous task. Further, such playlists rarely include media items with which a user in unfamiliar, yet may enjoy. Automatically-generated playlist or playlists curated by third parties can include media items with which a user in unfamiliar, but does not enjoy. Accordingly, in embodiments described below, playlists are automatically generated based on user interactions with media items and, in various implementations, a theme. Further, the playlists are automatically updated based on user interactions with the media items of the automatically-generated playlist, removing media items the user does not enjoy and adding media items the user is more likely to enjoy. Thus, over time, the playlist includes media items the user enjoys and frequently includes media items with which the user in unfamiliar, but is likely to enjoy. 
     Below,  FIGS.  1 A- 1 B,  2 , and  3    provide a description of example devices.  FIGS.  4 A- 4 B and  5 A- 5 CT  illustrate example user interfaces for playing back media items.

     Example Devices 
     Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments. 
     It will also be understood that, although the terms first, second, etc. are, in some instances, used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the scope of the various described embodiments. The first contact and the second contact are both contacts, but they are not the same contact, unless the context clearly indicates otherwise. 
     The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     As used herein, the term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Example embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch-screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch-screen display and/or a touchpad). 
     In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick. 
     The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user. 
     Attention is now directed toward embodiments of portable devices with touch-sensitive displays.  FIG.  1 A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display system  112  is sometimes called a “touch screen” for convenience, and is sometimes simply called a touch-sensitive display. Device  100  includes memory  102  (which optionally includes one or more computer readable storage mediums), memory controller  122 , one or more processing units (CPUs)  120 , peripherals interface  118 , RF circuitry  108 , audio circuitry  110 , speaker  111 , microphone  113 , input/output (I/O) subsystem  106 , other input or control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more intensity sensors  165  for detecting intensity of contacts on device  100  (e.g., a touch-sensitive surface such as touch-sensitive display system  112  of device  100 ). Device  100  optionally includes one or more tactile output generators  163  for generating tactile outputs on device  100  (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system  112  of device  100  or touchpad  355  of device  300 ). These components optionally communicate over one or more communication buses or signal lines  103 . 
     As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user&#39;s sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user&#39;s hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user&#39;s movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user. 
     It should be appreciated that device  100  is only one example of a portable multifunction device, and that device  100  optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in  FIG.  1 A  are implemented in hardware, software, firmware, or a combination thereof, including one or more signal processing and/or application specific integrated circuits. 
     Memory  102  optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory  102  by other components of device  100 , such as CPU(s)  120  and the peripherals interface  118 , is, optionally, controlled by memory controller  122 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU(s)  120  and memory  102 . The one or more processors  120  run or execute various software programs and/or sets of instructions stored in memory  102  to perform various functions for device  100  and to process data. 
     In some embodiments, peripherals interface  118 , CPU(s)  120 , and memory controller  122  are, optionally, implemented on a single chip, such as chip  104 . In some other embodiments, they are, optionally, implemented on separate chips. 
     RF (radio frequency) circuitry  108  receives and sends RF signals, also called electromagnetic signals.

     Audio circuitry  110 , speaker  111 , and microphone  113  provide an audio interface between a user and device  100 . Audio circuitry  110  receives audio data from peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to speaker  111 . Speaker  111  converts the electrical signal to human-audible sound waves. Audio circuitry  110  also receives electrical signals converted by microphone  113  from sound waves. Audio circuitry  110  converts the electrical signal to audio data and transmits the audio data to peripherals interface  118  for processing. Audio data is, optionally, retrieved from and/or transmitted to memory  102  and/or RF circuitry  108  by peripherals interface  118 . In some embodiments, audio circuitry  110  also includes a headset jack (e.g.,  212 ,  FIG.  2   ). The headset jack provides an interface between audio circuitry  110  and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone). 
     I/O subsystem  106  couples input/output peripherals on device  100 , such as touch-sensitive display system  112  and other input or control devices  116 , with peripherals interface  118 . I/O subsystem  106  optionally includes display controller  156 , optical sensor controller  158 , intensity sensor controller  159 , haptic feedback controller  161 , and one or more input controllers  160  for other input or control devices. The one or more input controllers  160  receive/send electrical signals from/to other input or control devices  116 . The other input or control devices  116  optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s)  160  are, optionally, coupled with any (or none) of the following: a keyboard, infrared port, USB port, stylus, and/or a pointer device such as a mouse. The one or more buttons (e.g.,  208 ,  FIG.  2   ) optionally include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons optionally include a push button (e.g.,  206 ,  FIG.  2   ). 
     Touch-sensitive display system  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch-sensitive display system  112 . Touch-sensitive display system  112  displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output corresponds to user-interface objects. 
     Touch-sensitive display system  112  has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic/tactile contact. Touch-sensitive display system  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch-sensitive display system  112  and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch-sensitive display system  112 . In an example embodiment, a point of contact between touch-sensitive display system  112  and the user corresponds to a finger of the user or a stylus. 
     Touch-sensitive display system  112  optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch-sensitive display system  112  and display controller  156  optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch-sensitive display system  112 . In an example embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, California. 
     Touch-sensitive display system  112  optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen video resolution is in excess of 400 dpi (e.g., 500 dpi, 800 dpi, or greater). The user optionally makes contact with touch-sensitive display system  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch-sensitive display system  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     Device  100  optionally also includes one or more optical sensors  164 .  FIG.  1 A  shows an optical sensor coupled with optical sensor controller  158  in I/O subsystem  106 . Optical sensor(s)  164  optionally include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor(s)  164  receive light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor(s)  164  optionally capture still images and/or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch-sensitive display system  112  on the front of the device, so that the touch screen is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user&#39;s image is obtained (e.g., for selfies, for videoconferencing while the user views the other video conference participants on the touch screen, etc.). 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG.  1 A  shows a contact intensity sensor coupled with intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor(s)  165  optionally include one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor(s)  165  receive contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ). In some embodiments, at least one contact intensity sensor is located on the back of device  100 , opposite touch-screen display system  112  which is located on the front of device  100 . 
     Device  100  optionally also includes one or more proximity sensors  166 .  FIG.  1 A  shows proximity sensor  166  coupled with peripherals interface  118 . Alternately, proximity sensor  166  is coupled with input controller  160  in I/O subsystem  106 . In some embodiments, the proximity sensor turns off and disables touch-sensitive display system  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  100  optionally also includes one or more tactile output generators  163 .  FIG.  1 A  shows a tactile output generator coupled with haptic feedback controller  161  in I/O subsystem  106 . Tactile output generator(s)  163  optionally include one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Tactile output generator(s)  163  receive tactile feedback generation instructions from haptic feedback module  133  and generates tactile outputs on device  100  that are capable of being sensed by a user of device  100 . In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device  100 ) or laterally (e.g., back and forth in the same plane as a surface of device  100 ). In some embodiments, at least one tactile output generator sensor is located on the back of device  100 , opposite touch-sensitive display system  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more accelerometers  167 , gyroscopes  168 , and/or magnetometers  169  (e.g., as part of an inertial measurement unit (IMU)) for obtaining information concerning the position (e.g., attitude) of the device.  FIG.  1 A  shows sensors  167 ,  168 , and  169  coupled with peripherals interface  118 . Alternately, sensors  167 ,  168 , and  169  are, optionally, coupled with an input controller  160  in I/O subsystem  106 . In some embodiments, information is displayed on the touch-screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers.

Furthermore, in some embodiments, memory  102  stores device/global internal state  157 , as shown in  FIGS.  1 A and  3   . Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch-sensitive display system  112 ; sensor state, including information obtained from the device&#39;s various sensors and other input or control devices  116 ; and location and/or positional information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., iOS, Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California In some embodiments, the external port is a Lightning connector that is the same as, or similar to and/or compatible with the Lightning connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California. 
     Contact/motion module  130  optionally detects contact with touch-sensitive display system  112  (in conjunction with display controller  156 ) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes software components for performing various operations related to detection of contact (e.g., by a finger or by a stylus), such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts or stylus contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts and/or stylus contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event. Similarly, tap, swipe, drag, and other gestures are optionally detected for a stylus by detecting a particular contact pattern for the stylus.

     Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory  102  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  102  optionally stores additional modules and data structures not described above. 
     In some embodiments, device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device  100 , the number of physical input control devices (such as push buttons, dials, and the like) on device  100  is, optionally, reduced. 
     The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device  100  to a main, home, or root menu from any user interface that is displayed on device  100 . In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad. 
       FIG.  1 B  is a block diagram illustrating example components for event handling in accordance with some embodiments. In some embodiments, memory  102  (in  FIG.  1 A ) or  370  ( FIG.  3   ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  136 ,  137 - 155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch-sensitive display system  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display system  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  167 , gyroscope(s)  168 , magnetometer(s)  169 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display system  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripheral interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views, when touch-sensitive display system  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture. 
     Hit view determination module  172  receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module  172  identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view. 
     Active event recognizer determination module  173  determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module  173  determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module  173  determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views. 
     Event dispatcher module  174  dispatches the event information to an event recognizer (e.g., event recognizer  180 ). In embodiments including active event recognizer determination module  173 , event dispatcher module  174  delivers the event information to an event recognizer determined by active event recognizer determination module  173 . In some embodiments, event dispatcher module  174  stores in an event queue the event information, which is retrieved by a respective event receiver module  182 . 
     In some embodiments, operating system  126  includes event sorter  170 . Alternatively, application  136 - 1  includes event sorter  170 . In yet other embodiments, event sorter  170  is a stand-alone module, or a part of another module stored in memory  102 , such as contact/motion module  130 . 
     In some embodiments, application  136 - 1  includes a plurality of event handlers  190  and one or more application views  191 , each of which includes instructions for handling touch events that occur within a respective view of the application&#39;s user interface. Each application view  191  of the application  136 - 1  includes one or more event recognizers  180 . Typically, a respective application view  191  includes a plurality of event recognizers  180 . In other embodiments, one or more of event recognizers  180  are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application  136 - 1  inherits methods and other properties. In some embodiments, a respective event handler  190  includes one or more of: data updater  176 , object updater  177 , GUI updater  178 , and/or event data  179  received from event sorter  170 . Event handler  190  optionally utilizes or calls data updater  176 , object updater  177  or GUI updater  178  to update the application internal state  192 . Alternatively, one or more of the application views  191  includes one or more respective event handlers  190 . Also, in some embodiments, one or more of data updater  176 , object updater  177 , and GUI updater  178  are included in a respective application view  191 . 
     A respective event recognizer  180  receives event information (e.g., event data  179 ) from event sorter  170 , and identifies an event from the event information. Event recognizer  180  includes event receiver  182  and event comparator  184 . In some embodiments, event recognizer  180  also includes at least a subset of: metadata  183 , and event delivery instructions  188  (which optionally include sub-event delivery instructions). 
     Event receiver  182  receives event information from event sorter  170 . The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device. 
     Event comparator  184  compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator  184  includes event definitions  186 . Event definitions  186  contain definitions of events (e.g., predefined sequences of sub-events), for example, event  1  ( 187 - 1 ), event  2  ( 187 - 2 ), and others. In some embodiments, sub-events in an event  187  include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event  1  ( 187 - 1 ) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event  2  ( 187 - 2 ) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display system  112 , and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers  190 . 
     In some embodiments, event definition  187  includes a definition of an event for a respective user-interface object. In some embodiments, event comparator  184  performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display system  112 , when a touch is detected on touch-sensitive display system  112 , event comparator  184  performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler  190 , the event comparator uses the result of the hit test to determine which event handler  190  should be activated. For example, event comparator  184  selects an event handler associated with the sub-event and the object triggering the hit test. 
     In some embodiments, the definition for a respective event  187  also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer&#39;s event type. 
     When a respective event recognizer  180  determines that the series of sub-events do not match any of the events in event definitions  186 , the respective event recognizer  180  enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture. 
     In some embodiments, a respective event recognizer  180  includes metadata  183  with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy. 
     In some embodiments, a respective event recognizer  180  activates event handler  190  associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer  180  delivers event information associated with the event to event handler  190 . Activating an event handler  190  is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer  180  throws a flag associated with the recognized event, and event handler  190  associated with the flag catches the flag and performs a predefined process. 
     In some embodiments, event delivery instructions  188  include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process. 
     In some embodiments, data updater  176  creates and updates data used in application  136 - 1 . For example, data updater  176  updates the telephone number used in contacts module  137 , or stores a video file used in video player module  145 . In some embodiments, object updater  177  creates and updates objects used in application  136 - 1 . For example, object updater  177  creates a new user-interface object or updates the position of a user-interface object. GUI updater  178  updates the GUI. For example, GUI updater  178  prepares display information and sends it to graphics module  132  for display on a touch-sensitive display. 
     In some embodiments, event handler(s)  190  includes or has access to data updater  176 , object updater  177 , and GUI updater  178 . In some embodiments, data updater  176 , object updater  177 , and GUI updater  178  are included in a single module of a respective application  136 - 1  or application view  191 . In other embodiments, they are included in two or more software modules. 
     It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices  100  with input-devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized. 
       FIG.  2    illustrates a portable multifunction device  100  having a touch screen (e.g., touch-sensitive display system  112 ,  FIG.  1 A ) in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or one or more styluses  203  (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device  100 . In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap. 
     Device  100  optionally also includes one or more physical buttons, such as “home” or menu button  204 . As described previously, menu button  204  is, optionally, used to navigate to any application  136  in a set of applications that are, optionally executed on device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on the touch-screen display. 
     In some embodiments, device  100  includes the touch-screen display, menu button  204 , push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , Subscriber Identity Module (SIM) card slot  210 , head set jack  212 , and docking/charging external port  124 . Push button  206  is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In some embodiments, device  100  also accepts verbal input for activation or deactivation of some functions through microphone  113 . Device  100  also, optionally, includes one or more contact intensity sensors  165  for detecting intensity of contacts on touch-sensitive display system  112  and/or one or more tactile output generators  163  for generating tactile outputs for a user of device  100 . 
       FIG.  3    is a block diagram of an example multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device  300  need not be portable. In some embodiments, device  300  is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child&#39;s learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device  300  typically includes one or more processing units (CPU&#39;s)  310 , one or more network or other communications interfaces  360 , memory  370 , and one or more communication buses  320  for interconnecting these components. Communication buses  320  optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device  300  includes input/output (I/O) interface  330  comprising display  340 , which is typically a touch-screen display. I/O interface  330  also optionally includes a keyboard and/or mouse (or other pointing device)  350  and touchpad  355 , tactile output generator  357  for generating tactile outputs on device  300  (e.g., similar to tactile output generator(s)  163  described above with reference to  FIG.  1 A ), sensors  359  (e.g., touch-sensitive, optical, contact intensity, proximity, acceleration, attitude, and/or magnetic sensors similar to sensors  112 ,  164 ,  165 ,  166 ,  167 ,  168 , and  169  described above with reference to  FIG.  1 A ). Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory  370  optionally includes one or more storage devices remotely located from CPU(s)  310 . In some embodiments, memory  370  stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory  102  of portable multifunction device  100  ( FIG.  1 A ), or a subset thereof. Furthermore, memory  370  optionally stores additional programs, modules, and data structures not present in memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  optionally stores drawing module  380 , presentation module  382 , word processing module  384 , website creation module  386 , disk authoring module  388 , and/or spreadsheet module  390 , while memory  102  of portable multifunction device  100  ( FIG.  1 A ) optionally does not store these modules. 
     Each of the above identified elements in  FIG.  3    are, optionally, stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory  370  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  370  optionally stores additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces (“UI”) that are, optionally, implemented on portable multifunction device  100 . 
       FIG.  4 A  illustrates an example user interface for a menu of applications on portable multifunction device  100  in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device  300 . In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator(s)  402  for wireless communication(s), such as cellular and Wi-Fi signals;   Time  404 ;   Bluetooth indicator  405 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Icon  416  for telephone module  138 , labeled “Phone,” which optionally includes an indicator  414  of the number of missed calls or voicemail messages;   Icon  418  for e-mail client module  140 , labeled “Mail,” which optionally includes an indicator  410  of the number of unread e-mails;   Icon  420  for browser module  147 , labeled “Browser”; and   Icon  422  for video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 , labeled “iPod”; and   
           Icons for other applications, such as:
           Icon  424  for IM module  141 , labeled “Text”;   Icon  426  for calendar module  148 , labeled “Calendar”;   Icon  428  for image management module  144 , labeled “Photos”;   Icon  430  for camera module  143 , labeled “Camera”;   Icon  432  for online video module  155 , labeled “Online Video”;   Icon  434  for stocks widget  149 - 2 , labeled “Stocks”;   Icon  436  for map module  154 , labeled “Map”;   Icon  438  for weather widget  149 - 1 , labeled “Weather”;   Icon  440  for alarm clock widget  169 - 6 , labeled “Clock”;   Icon  442  for workout support module  142 , labeled “Workout Support”;   Icon  444  for notes module  153 , labeled “Notes”; and   Icon  446  for a settings application or module, which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG.  4 A  are merely examples. For example, in some embodiments, icon  422  for video and music player module  152  is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG.  4 B  illustrates an example user interface on a device (e.g., device  300 ,  FIG.  3   ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG.  3   ) that is separate from the display  450 . Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  359 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  359  for generating tactile outputs for a user of device  300 . 
       FIG.  4 B  illustrates an example user interface on a device (e.g., device  300 ,  FIG.  3   ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG.  3   ) that is separate from the display  450 . Although many of the examples that follow will be given with reference to inputs on touch screen display  112  (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG.  4 B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) has a primary axis (e.g.,  452  in  FIG.  4 B ) that corresponds to a primary axis (e.g.,  453  in  FIG.  4 B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG.  4 B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG.  4 B,  460    corresponds to  468  and  462  corresponds to  470 ). In this way, user inputs (e.g., contacts  460  and  462 , and movements thereof) detected by the device on the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG.  4 B ) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein. 
     Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures, etc.), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse based input or a stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
     User Interfaces and Associated Processes 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device, such as portable multifunction device (PMD)  100  or device  300 , with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. 
       FIGS.  5 A- 5 CT  illustrate example user interfaces for playing back media items in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  6 A- 6 E,  7 A- 7 B,  8 A- 8 D, and  9 A- 9 E . Although some of the examples which follow will be given with reference to inputs on a touch-screen display (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface  451  that is separate from the display  450 , as shown in  FIG.  4 B . 
       FIG.  5 A  illustrates a user interface  501  for playing back media items using a portable multifunctional device  100 . The user interface  501  includes identifying text  511  indicating the media item being played back. For example, when the media item is a song, the identifying text  511  can include, for example and as shown in  FIG.  5 A , a song title, an artist, and an album title. When the media item is a podcast, the identifying text can, for example, include a podcast title, an episode number, an artist, or a date. When the media item is an audiobook, the identifying text can include, for example, a book title, an author, or a chapter number. When the media item is a movie, the identifying text can include, for example, a title, a release date, or a production studio. The media item can be other types of content besides a song, podcast, audiobook, or movie and the identifying text can include other types of information. 
     The user interface  501  includes a number of playback affordances, described in detail below, for manipulating playback of the media item and/or other media items. The playback affordances can include a play-pause affordance  521  for pausing and resuming playback of the media item being played back, a reverse affordance  522  for starting playback of a prior media item, a forward affordance  523  for starting playback of a next media item, a volume affordance  524  for changing the volume of sound associated with the media item, and a scrubbing affordance  525  for changing a playback time of playback of the media item. 
     The user interface  501  includes an image  531  associated with the media item. The image  531  can be stored in association with the content of the media item. When the media item is a song, the image  531  can, for example, be album cover art associated with an album upon which the song appears. In some implementations, the image  531  can be a photograph of the artist that performs the song. When the media item is a podcast, the image  531  can be a logo associated with the podcast and/or the performers. When the media item is an audiobook, the image  531  can be book cover art. In some implementations, when an image is not stored in association with the content of the media item, a placeholder image can be used. The placeholder image can be, for example, a default image or a generated image (e.g., a monogram). 
     The image  531  is displayed within a display region of the display of the portable multifunctional device  100 . Thus, the image  531  occupies or spans the display region of the display. As described further below, the display region occupied by the image  531  can change as the image  531  changes size, location, and/or shape. 
     The identifying text  511  and the pause-play affordance  521  form a playback status indicator regarding playback of the media item. When the pause-play affordance  521  is in a press-to-pause state, or simply, a pause state (as shown in  FIG.  5 A ), the playback status indicator indicates that the media item indicated by the identifying text  511  is being played. When the pause-play affordance  521  is in a press-to-play state, or simply, a play state (as shown in  FIG.  5 C ), the playback status indicator indicates that the media item identified by the identifying text  511  is paused. It is to be appreciated that playing back a media item includes either or both of playing or pausing the media item. Thus, even when playback of the media item is paused, the portable multifunctional device  100  is playing back the media item. 
     When the media item is being played, the image  531  is surrounded by a border  531 A (or a shadow or other visual effect that causes the image to appear to be lifted off from a background of the user interface in a virtual z direction) which also serves (in part) as a playback status indicator. As described below (and shown in  FIG.  5 C ), when the media item is paused, the image  531  is not surround by the border  531 A. In various implementations, the border  531 A can be replaced with other playback status indicators associated with the image. For example, in some implementations, a brightness, contrast, or color of the image  531  is changed based on the playback status of the media item. In  FIG.  5 A , the border  531 A surrounds the image  531 . In some implementations, the border  531 A or another playback status indicator associated with the image  531  is present only of two sides of the image or on one side of the image. 
       FIG.  5 B  illustrates the user interface  501  of  FIG.  5 A  with a touch  581 A detected at a location of the image  531  (e.g., within the display region). The touch  581 A is an input interacting with the image. The touch  581 A includes a first portion (touchdown of a contact on the image  531  on the touch-sensitive display of the portable multifunctional device  100 ) and a second portion (liftoff of the contact from the touch-sensitive display of the portable multifunctional device  100 ). 
       FIG.  5 C  illustrates the user interface  501  in response to detecting the touch  581 A at the location of the image  531  in  FIG.  5 B . In response to detecting the touch  581 A at the location of the image  531 , the pause-play affordance  521  is changed to a play state and the size of the image  531  is reduced (e.g., the size of the display region is reduced). As shown in  FIG.  5 C , the location of the image  531  (e.g., the center of the image  531 ) is unchanged. Also in response to detecting the touch  581 A at the location of the image  531 , the border  531 A ceases to be displayed. The pause-play affordance  521  changing to the play state (and ceasing display of the border  531 A) indicates that playback of the media item is paused. 
     In some implementations, the appearance of the image  531  on the display is adjusted (e.g., the size is reduced) in response to and in accordance with a first portion of the touch  581 A (e.g., touchdown of the contact) and playback of content on the device is changed (e.g., playback of the media item is paused) in response to and in accordance with a second portion of the touch  581 A (e.g., liftoff of the contact). 
       FIG.  5 D  illustrates the user interface  501  of  FIG.  5 C  with a touch  581 B detected at a location of the image  531  (e.g., within the display region). The touch  581 B is an input interacting with the image  531 . The touch  581 B includes a first portion (touchdown of a contact on the image  531  on the touch-sensitive display of the portable multifunctional device  100 ) and a second portion (liftoff of the contact from the touch-sensitive display of the portable multifunctional device  100 ). 
       FIG.  5 E  illustrates the user interface  501  in response to detecting the touch  581 B at the location of the image  531  in  FIG.  5 D . In response to detecting the touch  581 B at the location of the image  531 , the pause-play affordance  521  is changed back to a pause state and the size of the image  531  is increased (e.g., the size of the display region is increased) back to the size of the image  531  in  FIG.  5 A . As shown in  FIG.  5 E , the location of the image  531  (e.g., the center of the image  531 ) is unchanged. Also in response to detecting the touch  581 B at the location of the image  531 , the border  531 A is, once again, displayed. The pause-play affordance  521  changing to the pause state (and resuming display of the border  531 A) indicates that playback of the media item is resumed. 
     In some implementations, the appearance of the image  531  on the display is adjusted (e.g., the size is increased) in response to and in accordance with a first portion of the touch  581 B (e.g., touchdown of the contact) and playback of content on the device is changed (e.g., playback of the media item is resumed) in response to and in accordance with a second portion of the touch  581 B (e.g., liftoff of the contact). 
       FIG.  5 F  illustrates the user interface  501  of  FIG.  5 E  with a touch  581 C detected at a location of the pause-play affordance  521 . The touch  581 C is a pause-play user input interacting with the pause-play affordance  521 . The touch  581 C includes a first portion (touchdown of a contact on the pause-play affordance  521  on the touch-sensitive display of the portable multifunctional device  100 ) and a second portion (liftoff of the contact from the touch-sensitive display of the portable multifunctional device  100 ). 
       FIG.  5 G  illustrates the user interface  501  in response to detecting the touch  581 C at the location of the pause-play affordance  521  in  FIG.  5 F . In response to detecting the touch  581 C at the location of the pause-play affordance  521 , the pause-play affordance  521  is changed to a play state and the size of the image  531  is reduced (e.g., the size of the display region is reduced). As shown in  FIG.  5 G , the location of the image  531  (e.g., the center of the image  531 ) is unchanged. Also in response to detecting the touch  581 C at the location of the pause-play affordance  521 , the border  531 A ceases to be displayed. The pause-play affordance  521  changing to the pause state (and ceasing display of the border  531 A) indicates that playback of the media item is paused. 
     In some implementations, the appearance of the image  531  on the display is adjusted (e.g., the size is decreased) in response to and in accordance with a first portion of the touch  581 C (e.g., touchdown of the contact) and playback of content on the device is changed (e.g., playback of the media item is paused) in response to and in accordance with a second portion of the touch  581 C (e.g., liftoff of the contact). 
       FIG.  5 H  illustrates the user interface  501  of  FIG.  5 G  with a touch  581 D detected at a location of the pause-play affordance  521 . The touch  581 D is a pause-play user input interacting with the pause-play affordance  521 . The touch  581 D includes a first portion (touchdown of a contact on the pause-play affordance  521  on the touch-sensitive display of the portable multifunctional device  100 ) and a second portion (liftoff of the contact from the touch-sensitive display of the portable multifunctional device  100 ). 
       FIG.  5 I  illustrates the user interface  501  in response to detecting the touch  581 D at the location of the pause-play affordance  521  in  FIG.  5 H . In response to detecting the touch  581 D at the location of the pause-play affordance  521 , the pause-play affordance  521  is changed back to a pause state and the size of the image  531  is increased (e.g., the size of the display region is increased) back to the size of the image  531  in  FIG.  5 A . As shown in  FIG.  5 I , the location of the image  531  (e.g., the center of the image  531 ) is unchanged. Also in response to detecting the touch  581 D at the location of the pause-play affordance  521 , the border  531 A is, once again, displayed. The pause-play affordance  521  changing to the pause state (and resuming display of the border  531 A) indicates that playback of the media item is resumed. 
     In some implementations, the appearance of the image  531  on the display is adjusted (e.g., the size is increased) in response to and in accordance with a first portion of the touch  581 D (e.g., touchdown of the contact) and playback of content on the device is changed (e.g., playback of the media item is resumed) in response to and in accordance with a second portion of the touch  581 D (e.g., liftoff of the contact). 
     Thus, touching the image  531  and touching the pause-play affordance  521  have the same (or a substantially similar) effect. In particular, touching either the image  531  or the pause-play affordance  521  results in switching between pausing and playback of the media item. Further, touching either the image  531  or the pause-play affordance  521  results in a resizing of the image  531  and toggling of display of the border  531 A. 
     Because touching the image  531  and touching the pause-play affordance  521  can have a substantially similar effect, in some implementations, the user interface  501  does not include a pause-play affordance, or at least, does not include a pause-play affordance when the image  531  is displayed. Such a user interface  501  excluding a pause-play affordance may be particularly beneficial in portable multifunctional devices with small touch-sensitive displays (e.g., less than 5 square inches, less than 3 square inches, or less than 2 square inches) as may be found in portable music players or smartwatches. 
       FIG.  5 J  illustrates the user interface  501  of  FIG.  5 I  with a swipe  581 E detected moving over the image  531 . The swipe  581 E is a user input interacting with the image  531 . The swipe  581 E includes a first portion (movement of a contact on the touch-sensitive display of the portable multifunctional device  100  a first distance) and a second portion (movement of the contact on the touch-sensitive display of the portable multifunctional device  100  a second distance). The swipe  581 E can include additional portions, such as contact on the touch-sensitive display or liftoff of the contact from the touch-sensitive display. 
       FIG.  5 K  illustrates the user interface  501  in response to detecting a first portion of the swipe  581 E over the image  531 . In response to detecting the first portion of the swipe  581 E over the image  531 , the image  531  is moved in accordance with the direction of the swipe  581 E (e.g., the location of the display region is changed). In particular, when the swipe  581 E moves from a first location to a second location to the left of the first location, the image is moved to the left. Conversely, when the swipe  581 E moves from a first location to a second location to the right of the second location, the image is moved to the right. 
     In some implementations, the appearance of the image  531  on the display is adjusted (e.g., the image  531  is moved) in response to and in accordance with a first portion of the swipe  581 E (e.g., a first distance) and playback of content on the device is changed (e.g., playback of a second media item is started) in response to and in accordance with a second portion of the swipe  581 E (e.g., a second distance or liftoff of the contact) as described below. 
       FIG.  5 L  illustrates the user interface  501  of  FIG.  5 K  with an additional portion of the swipe  581 E detected. In response to the additional portion of the swipe  581 E, the image  531  is moved further in accordance with the direction of the swipe. Further, a second image  532  (with a corresponding border  532 A) associated with a second media item is displayed as the image  531  associated with the first media item is sliding off the display. 
       FIG.  5 M  illustrates the user interface  501  in response to detecting the second portion of the swipe  581 E over the image  531 . In response to detecting the second portion of the swipe  581 E over the image  531 , the identifying text  511  for the first media item is replaced with identifying text  512  for the second media item. Further, the image  531  associated with the first item is completely replaced with the image  532  associated with the second media item. Thus, the identifying text  512  (and the pause-play affordance  521 ) form a playback status indicator indicating that the portable multifunctional device  100  is playing back the second media item. In some implementations, starting playback of the second media item includes crossfading between the media item and the second media item while sliding the image  531  associated with the first media item off the display (e.g., in  FIG.  5 L ). 
       FIGS.  5 J- 5 M  illustrate a swipe  581 E to the left causing playback of a next media item in a queue. In some implementations, a swipe over the image  531  to the right causes playback of a prior media item in the queue. Thus, in some implementations, starting playback of the second media item includes, in accordance with a determination that the movement of a contact is in a first direction, selecting a prior media item in a queue as the second media item and, in accordance with a determination that the movement of the contact is in a second direction that is different from (e.g., opposite to) the first direction, selecting a next media item in the queue as the second media item. 
       FIG.  5 N  illustrates the user interface  501  of  FIG.  5 M  with a touch  581 F detected at a location of the forward affordance  523 . The touch  581 F is a skip user input interacting with the forward affordance  523 . The touch  581 F includes a first portion (touchdown of a contact on the forward affordance  523  on the touch-sensitive display of the portable multifunctional device  100 ) and a second portion (liftoff of the contact from the touch-sensitive display of the portable multifunctional device  100 ). 
       FIG.  5 O  illustrates the user interface  501  in response to detecting the touch  581 F at the location of the forward affordance  523  in  FIG.  5 N . In response to detecting the touch  581 F at the location of the forward affordance  523 , the image  532  is moved to left. In some implementations, the appearance of the image  532  on the display is adjusted (e.g., the image  532  is moved) in response to and in accordance with a first portion of the touch  581 F (e.g., touchdown of the contact) and playback of content on the device is changed (e.g., playback of a second media item is started) in response to and in accordance with a second portion of the touch  581 F (e.g., liftoff of the contact) as described below. 
       FIG.  5 P  illustrates the user interface  501  of  FIG.  5 O  at a slightly later time. In response to detecting the touch  581 F at the location of the forward affordance in  FIG.  5 N , the image  532  is moved to left (as shown in  FIG.  5 O ). In  FIG.  5 P , the image  532  has moved further to left and an image  533  (with a corresponding border  533 A) associated with a third media item is partially displayed on the right of the display. 
       FIG.  5 Q  illustrates the user interface of  FIG.  5 P  at a slightly later time. In  FIG.  5 Q , the identifying text  512  for the second media item is replaced with identifying text  513  for the third media item. Further, the image  532  associated with the second media item is completely replaced with the image  533  associated with the third media item. Thus, the identifying text  513  (and the pause-play affordance  521 ) form a playback status indicator indicating that the portable multifunctional device  100  is playing back the third media item. 
       FIGS.  5 N- 5 Q  illustrate a touch  581 F at the location of the forward affordance  523  causing playback of a next media item in a queue. In some implementations, a touch at location of the reverse affordance  522  (also a skip user input) causes playback of a prior media item in the queue. Thus, in some implementations, a skip user input is detected interacting with one of one or more skip affordances (e.g., the reverse affordance  522  and the forward affordance  523 ). In response to a first portion of the skip user input, the image  532  is moved in accordance with the one of the one or more skip affordances. For example, if the skip user input is detected interacting with the forward affordance  523 , the image moves to the left and if the skip user input is detected interacting with the reverse affordance  522 , the image moves to the right. Further, in response to a second portion of the skip user input, playback of another media item is started in accordance with the one of the one or more skip affordances. For example, if the skip user input is detected interacting with the forward affordance  523 , a next media item in the queue is played and if the skip user input is detected interacting with the reverse affordance  522 , a prior media item in the queue is played. 
       FIG.  5 R  illustrates the user interface  501  of  FIG.  5 Q  with a vertical multi-touch drag  581 G detected over the image  533 . The vertical multi-touch drag  581 G is a user input interacting with the image  533 . The vertical multi-touch drag  581 G includes a first portion (touchdown of the contacts on the touch-sensitive display of the portable multifunctional device  100 ) and a second portion (movement of the contacts on the touch-sensitive display of the portable multifunctional device  100 ). The vertical multi-touch drag  581 G can include additional portions, such as liftoff of the contact from the touch-sensitive display. The second portion of the vertical multi-touch drag  581 G can include multiple sub-portions (themselves portions), such as movement a first distance and movement a second distance. 
       FIG.  5 S  illustrates the user interface  501  in response to detecting the vertical multi-touch drag  581 G over the image  533  in  FIG.  5 R . In response to detecting the vertical multi-touch drag  581 G over the image  533 , the shape of the image  533  is changed. As shown in  FIG.  5 S , a vertical multi-touch drag  581 G in a downward direction results in a downward tilting of the image  533 . Thus, the shape of the image  533  is skewed. Also in response to detecting the vertical multi-touch drag  581 G over the image, the volume affordance  524  is moved from its original location  524 A indicating that a volume of the playback of the third media item has been reduced. 
       FIG.  5 T  illustrates the user interface of  FIG.  5 Q  with a horizontal multi-touch drag  581 H detected over the image  533 . The horizontal multi-touch drag  581 H is a user input interacting with the image  533 . The horizontal multi-touch drag  581 H includes a first portion (touchdown of the contacts on the touch-sensitive display of the portable multifunctional device  100 ) and a second portion (movement of the contacts on the touch-sensitive display of the portable multifunctional device  100 ). The horizontal multi-touch drag  581 H can include additional portions, such as liftoff of the contact from the touch-sensitive display. The second portion of the horizontal multi-touch drag  581 H can include multiple sub-portions (themselves portions), such as movement a first distance and movement a second distance. 
       FIG.  5 U  illustrates the user interface  501  in response to detecting a first portion of the horizontal multi-touch drag  581 H over the image  533  in  FIG.  5 T . In response to detecting the horizontal multi-touch drag  581 H over the image  533 , the shape of the image  533  is changed. As shown in  FIG.  5 U , a horizontal multi-touch drag  581 H in a rightward direction results in a rightward tilting of the image  533 . Thus, the shape of the image  533  is skewed. Also in response to detecting the horizontal multi-touch drag  581 H over the image, the scrubbing affordance  525  has changed from its original location  525 A indicating that a playback time of the third media item has been changed. 
       FIG.  5 V  illustrates the user interface  501  in response to detecting a second portion of the horizontal multi-touch drag  581 H over the image  533  in  FIG.  5 T . In response to detecting the second portion of the horizontal multi-touch drag  581 H over the image  533 , the shape of the image  533  is further changed. In particular, the shape of the image  533  is further skewed as the image is tilted in accordance with the distance of the horizontal multi-touch drag  581 H. Also in response to detecting the second portion of the horizontal multi-touch drag  581 H over the image  533 , the scrubbing affordance  525  has changed further from its original location  525 A indicating that a playback time of the third media item has been further changed. Thus, a magnitude of the change in the playback time and the magnitude of the change in the shape of the image are both proportional to a distance of the horizontal multi-touch drag  581 H (e.g., a magnitude of the movement of the multi-touch contact). 
       FIGS.  5 R- 5 V  show the effects of different multi-touch drags. In general, detecting an input interacting with the image  533  can include detecting movement of a multi-touch contact over the image  533 . In some implementations, the appearance of the image  533  on the display is adjusted (e.g., the shape of the image  533  is changed) in response to and in accordance with a first portion of the multi-touch contact  581 G and playback of content on the device is changed (e.g., a non-binary characteristic is changed) in response to and in accordance with a second portion of the multi-touch drag  581 G (e.g., a second distance of the contact). The non-binary characteristic can include, for example, volume (as shown in  FIGS.  5 R- 5 S ), playback time (as shown in  FIGS.  5 T- 5 V ), an equalization setting, or any other playback characteristic having more than two values. 
     In some implementations, the portable multifunctional device  100  detects a multi-touch contact and, in accordance with a determination that the movement is along a first axis (e.g., vertical), changes a first non-binary playback characteristic (e.g., volume) and, in accordance with a determination that the movement is along a second axis (e.g., horizontal), changes a second non-binary playback characteristic (e.g., playback time). 
     Although  FIGS.  5 R- 5 V  illustrate increasing the volume and playback time with downward and rightward multi-touch drags, it is to be appreciated that the volume and playback time can be similarly decreased with upward and leftward multi-touch drags, respectively. 
       FIG.  5 W  illustrates the user interface of  FIG.  5 Q  with a drag  581 I detected at the location of the scrubbing affordance  525 . The drag  581 I includes a first portion (touchdown of the contact on the touch-sensitive display of the portable multifunctional device  100 ) and a second portion (movement of the contact on the touch-sensitive display of the portable multifunctional device  100 ). The drag  581 I can include additional portions, such as liftoff of the contact from the touch-sensitive display. The second portion of the drag  581 I can include multiple sub-portions (themselves portions), such as movement a first distance and movement a second distance. 
       FIG.  5 X  illustrates the user interface  501  in response to detecting the drag  581 I at the location of the scrubbing affordance in  FIG.  5 W . The image  533  (retaining its border  533 A) is reduced in size and moved upward. In the space provided, a scrubbing waveform  525 B is displayed indicative of the magnitude of the audio of the third media item at various playback times. Also in the space provided, scrubbing speed information  525 C is displayed. When the portable multifunction device  100  detects the drag continuing leftward or rightward, the portable multifunctional device  100  changes the playback time of the third media item. 
     As described above, interacting with the image  533  and touching the playback affordances  521 - 525  can have the same (or a substantially similar) effect. Thus, in some implementations, the user interface  501  does not include one or more of the playback affordances  521 - 525 , or at least, does not include one or more of the playback affordances  521 - 525  when the image  533  is displayed. In some implementations, the user interface  501  does not include any of the playback affordances  521 - 525  when the image  533  is displayed. Such a user interface  501  excluding playback affordances may be particularly beneficial in portable multifunctional devices with small touch-sensitive displays (e.g., less than 5 square inches, less than 3 square inches, or less than 2 square inches) as may be found in portable music players or smartwatches. 
       FIG.  5 Y  illustrates the user interface of  FIG.  5 Q  with a swipe  581 J detected at the location of the image  533 . The swipe  581 J is a user input interacting with the image  533 . The swipe  581 J includes a first portion (movement of a contact on the touch-sensitive display of the portable multifunctional device  100  a first distance) and a second portion (movement of the contact on the touch-sensitive display of the portable multifunctional device  100  a second distance). The swipe  581 J can include additional portions, such as contact on the touch-sensitive display or liftoff of the contact from the touch-sensitive display. 
       FIG.  5 Z  illustrates the user interface  501  in response to detecting a first portion of the swipe  581 J (e.g., movement a first distance) at the location of the image  533  in  FIG.  5 Y . The image  533  (retaining its border  533 A), the identifying text  513 , and the various playback affordances  521 - 525  are together moved upward as a single unit, referred to as a now-playing pane  541 . In the space provided, a lyrics pane  542  is displayed and a queue pane  543  is partially displayed. The lyrics pane  542  includes a lyrics toggle affordance  542 A (described further below) for toggling the display of lyrics of the media item. 
       FIG.  5 AA  illustrates the user interface  501  in response to detecting a second portion of the swipe  581 J (e.g., movement a first distance) at the location of the image in  FIG.  5 Y . The now-playing pane  541 , lyrics pane  542 , and queue pane  543  are moved upwards as compared to  FIG.  5 Z .  FIG.  5 AA  illustrates that the queue pane  543  includes a queue representation  543 A (described further below) indicative of upcoming media items. 
       FIG.  5 AB  illustrates the user interface  501  in response to detecting a third portion of the swipe  581 J (e.g., liftoff) at the location of the image in  FIG.  5 Y . In FIG.  5 AB, the now-playing pane  541  is no longer displayed, the lyrics pane  542  is displayed at the top of the display, the queue pane  543  is fully displayed, a suggestions pane  544  is displayed, and an other information pane  545  is partially displayed. The suggestions pane  544  includes suggestion representations  544 A displaying suggested media items selected based on the currently selected media item (e.g., in  FIG.  5 AB , the third media item). The suggested media items can also be based on other implicit and explicitly determined user preferences, such as media items by the same artist, media items in the same genre, or media items played by other users connected via a social network. The other information pane  545  can display other information related to the media item, such as awards won by the media item or a biography of the artist of the media item. The other information pane  545  can also (or alternatively) display information unrelated to the media item. 
     Thus,  FIGS.  5 Y- 5 AB  illustrates that, in response to detecting the swipe  581 J over the image  533 , the image  533  is moved and related media items are displayed (e.g., media items related to the media item being played back). The related media items can include media items in a queue with the media item (as in the queue pane  543 ) and/or suggested media items (as in the suggestions pane  544 ). 
       FIG.  5 AC  illustrates the user interface  501  of  FIG.  5 AC  with a touch  581 K detected at the location of the lyrics toggle affordance  542 A. The touch  581 K includes a first portion (touchdown of a contact on the image on the touch-sensitive display of the portable multifunctional device  100 ) and a second portion (liftoff of the contact from the touch-sensitive display of the portable multifunctional device  100 ). 
       FIG.  5 AD  illustrates the user interface  501  in response to detecting the touch  581 K at the location of the lyrics toggle affordance  542 A in  FIG.  5 AC . In  FIG.  5 AD , the lyrics pane  542  is expanded to display lyrics  542 B of the media item. The queue pane  543  and suggestions pane  544  are moved downward by this expansion. Further, the lyrics toggle affordance  542 A is changed from a show state (e.g., as in  FIG.  5 AC ) to a hide state. 
     In some implementations, toggling between showing and hiding lyrics of the media item is persistent. Thus, when a next media item is being played back at a later time and the user interface  501  fully displays the now-playing pane  541 , an upward swipe will display the lyrics pane  542  with the lyrics  542 B of the next media item without detecting an additional touch of the lyrics toggle affordance  542 A. 
       FIG.  5 AE  illustrates the user interface  501  of  FIG.  5 AD  with a swipe  581 L detected in the lyrics pane  542 . Although  FIG.  5 AE  shows the swipe  581 L as originating in the lyrics pane  542 , a similar effect can be realized with a swipe in other panes, such as the queue pane  543  or the suggestions pane  544 . The swipe  581 L includes a first portion (e.g., movement of a contact on the touch-sensitive display of the portable multifunctional device  100  a first distance) and a second portion (e.g., movement of the contact on the touch-sensitive display of the portable multifunctional device  100  a second distance). The swipe  581 L can include additional portions, such as contact on the touch-sensitive display or liftoff of the contact from the touch-sensitive display. 
       FIG.  5 AF  illustrates the user interface  501  in response to detecting a first portion of the swipe  581 L (e.g., movement of the contact a first distance) in the lyrics pane  542 . The lyrics pane  542  and queue pane  543  have moved down and the suggestions pane  544  has been removed. In the space provided, the now-playing pane  541  is partially displayed. 
       FIG.  5 AG  illustrates the user interface  501  in response to detecting a second portion of the swipe  581 L (e.g., liftoff of the contact) in the lyrics pane  542 . In  FIG.  5 AG , the lyrics pane  542  and queueing pane  543  are no longer displayed and the now-playing pane  541  fills the display. 
       FIG.  5 AH  illustrates the user interface of  FIG.  5 AG  with a swipe  581 M detected over the image  533 . The swipe  581 M includes a first portion (e.g., movement of a contact on the touch-sensitive display of the portable multifunctional device  100  a first distance) and a second portion (e.g., movement of the contact on the touch-sensitive display of the portable multifunctional device  100  a second distance). The swipe  581 M can include additional portions, such as contact on the touch-sensitive display or liftoff of the contact from the touch-sensitive display. 
       FIG.  5 AI  illustrates the user interface  501  in response to detecting a first portion of the swipe  581 M (e.g., movement of the contact a first distance) over the image  533 . The now-playing pane  541  is moved downward, revealing a playlist pane  546 . Between the now-playing pane  541  and the playlist pane  546  is a miniplayer user interface  540 . The miniplayer user interface  540  includes identifying text  513 A indicative of the currently selected media item (e.g., in  FIG.  5 AI , the third media item). The miniplayer user interface  540  includes a pause-play affordance  521 A providing the same functionality as the pause-play affordance  521  of the now-playing pane  541 . The miniplayer user interface  550  includes a mini-image  533 B, a reduced-size version of the image  533  associated with the third media item. 
     In some implementations, the mini-image  533 B operates as an affordance providing the same functionality as the pause-play affordance  521 A. Thus, in some implementations, the miniplayer user interface  550  does not include the pause-play affordance  521 A. In some implementations, the miniplayer user interface  550  includes other affordances other than those shown in  FIG.  5 AI . 
       FIG.  5 AJ  illustrates the user interface  501  in response to detecting a second portion of the swipe  581 M (e.g., movement of the contact a second distance) over the image  533 . In  FIG.  5 AJ , the now-playing pane  541  is moved further downward, revealing more of the playlist pane  546 . The miniplayer user interface  550  remains between the now-playing pane  541  and the playlist pane  546 . 
       FIG.  5 AK  illustrates the user interface  501  in response to detecting a third portion of the swipe  581 M (e.g., liftoff of the contact) over the image  533 . In  FIG.  5 AK , the now-playing pane  541  is no longer displayed and the miniplayer user interface  550  is displayed at the bottom of the display. The playlist pane  546  is fully displayed at the top of the display. Beneath the playlist pane  546 , the suggestions pane  544  is partially displayed. 
       FIG.  5 AL  illustrates the user interface  501  with a touch  581 N detected within the miniplayer user interface  550 . The touch  581 N is not detected at the location of the mini-image  533 B or the pause-play affordance  521 A. The touch  581 N includes a first portion (touchdown of a contact on the image on the touch-sensitive display of the portable multifunctional device  100 ) and a second portion (liftoff of the contact from the touch-sensitive display of the portable multifunctional device  100 ). 
       FIG.  5 AM  illustrates the user interface  501  in response to detecting the touch  581 N within the miniplayer user interface  550 . In  FIG.  5 AM , the miniplayer user interface  550  is moved upward as compared to its location in  FIG.  5 AL . In space provided, the now-playing pane  541  is partially displayed.

The amounts of storage indicated by the media storage reservation size affordances  576 C are, in some implementations, based on a size of the storage device. For example, for a storage device with 32 GB of storage space, the media storage reservation size affordances  576 C can (as shown in  FIG.  5 BZ ) include affordances for no minimum, 1 GB, 2 GB, and 4 GB. For a storage device with 4 GB of storage space, the media storage reservation size affordances  576 C can include affordances for no minimum, 100 MB, 250 MB, and 1 GB. 
       FIG.  5 BZ  illustrates a touch  582 G detected at a location of a 2 GB media storage reservation size affordance of the plurality of media storage reservation size affordances  576 C. 
       FIG.  5 CA  illustrates the user interface  501  in response to detecting the touch  582 G at the location of the 2 GB storage reservation size affordance. In  FIG.  5 CA , the optimize storage feature is activated, as indicated by the optimize storage feature toggle  576 A in the on state. Further, the media storage reservation size is set to 2 GB, as indicated by the media storage reservation size affordances  576 C. 
     When the optimize storage feature is active, the portable multifunctional device  100  can, without further user input, delete media files to free storage of a storage device of the portable multifunctional device  100  while maintaining at least the media storage reservation size of media files. For example, as shown in  FIG.  5 CA , the portable multifunctional device  100  is storing 6.4 GB of media files, but has reserved 2 GB for media files. Thus, the portable multifunctional device  100  can, without further user input, delete up to 4.4 GB of media files in order to perform other storage operations. However, the portable multifunctional device  100  does not delete more than 4.4 GB of media files without further user input. 
     In operation, the portable multifunctional device  100  can detect the occurrence of a condition that corresponds to a request to free storage (e.g., the request to download the media files of the album in  FIG.  5 BT  when there is insufficient storage to complete the download as indicated by  FIG.  5 BW ). In accordance with a determination that the amount of storage used by media files (e.g., 6.4 GB in  FIG.  5 CA ) is greater than the minimum amount of media storage that has been reserved for media items (e.g., 2 GB in  FIG.  5 CA ), the portable multifunctional device  100  can delete one or more of the stored media items. In accordance with a determination that the amount of storage used by media files is less than the minimum amount of media storage reserved for media items, the portable multifunctional device  100  can forgo deleting media items from the device. 
     It is to be understood that although the media storage reservation size limits the amount of media items that can be deleted without further user input, the media storage reservation size does not set of a maximum limit for the amount of media files that can be stored on the device. 
       FIG.  5 CA  illustrates a touch  582 H detected at a music settings affordance  576 D for returning to the music settings user interface  575 . 
       FIG.  5 CB  illustrates the user interface  501  in response to detecting the touch  582 H at the music settings affordance  576 D. The music settings user interface  575  (in contrast to  FIG.  5 BX ) includes a media deletion warning  575 C indicating that, due to the optimize storage feature being activated and the media storage reservation size being less than the amount of storage used by media files, media files may be deleted without further user input. 
       FIG.  5 CB  illustrates a touch  582 I at a location of the auto-add toggle affordance  575 A. 
       FIG.  5 CC  illustrates the user interface  501  in response to detecting the touch  582 I at the location of the auto-add toggle affordance  575 A.

       FIG.  5 CJ  illustrates the user interface  501  including a playlist user interface  590 . The playlist user interface  590  can be displayed in response to a number of inputs (not shown) navigating to the playlist user interface  590 . The playlist user interface  590  includes a plurality of playlist affordances  591  for displaying representations of respective playlists which include affordances for playing back the media items of the playlist. 
     The playlist affordances  591  include a first automatically-generated playlist affordance  592 A for displaying a representation of a first automatically-generated playlist and a second automatically-generated playlist affordance  592 B for displaying a representation of a second automatically-generated playlist. 
       FIG.  5 CJ  illustrates a touch  582 N detected at a location of the first automatically-generated playlist affordance  592 A. 
       FIG.  5 CK  illustrates the user interface  501  in response to detecting the touch  582 N at the location of the first automatically-generated playlist affordance  592 A. The user interface  501  includes a representation of the first automatically-generated playlist  593 . The representation of the first automatically-generated playlist  593  includes representations of a first set of media items  596  selected for inclusion in the first automatically-generated playlist based on first playlist generation criteria for the first automatically-generated playlist. 
     The representation of the first automatically-generated playlist  593  includes identifying information  594  that includes, in  FIG.  5 CK , a title of the first automatically-generated playlist, the number of media items in the first automatically-generated playlist, and a time the automatically-generated playlist was last updated. 
     The representation of the first automatically-generated playlist  593  include a save affordance  595 A for saving the first set of media items as a user playlist. The representation of the first automatically-generated playlist  593  includes a share affordance  595 B for sharing the first set of media items as a shared playlist. 
       FIG.  5 CK  illustrates a touch  528 O detected at a location of the save affordance  595 A. 
       FIG.  5 CL  illustrates the user interface  501  in response to detecting the touch  528 O at the location of the save affordance  595 A. The user interface  501  includes the playlist user interface  590 . The playlist user interface includes a saved affordance  591 A corresponding to a user playlist of the first set of media items in the first automatically-generated playlist. 
       FIG.  5 CL  illustrates a state in which a first update criterion has been met. In various implementations, the first update criterion specifies that the first set of media items is to be updated on a predefined day of the week. 
       FIGS.  5 CL- 5 CP  illustrate an update animation that occurs in response to the first update criterion having been met. In  FIG.  5 CL , the first automatically-generated playlist affordance  592 A includes a first plurality of images respectively associated with a plurality of the first set of media items. In  FIG.  5 CP , the first automatically-generated playlist affordance  592 A includes an updated first plurality of images respectively associated with a plurality of an updated first set of media item. 
     Thus,  FIGS.  5 CL- 5 CP  illustrate an update animation in which one or more of the first plurality of images are replaced with one or more of the updated first plurality of images. The animation indicates that new media items have been added to the first automatically-generated playlist. 
     Although  FIG.  5 CL- 5 CP  illustrate an update animation in which one or more of the first plurality of images are flipped over to review one or more of the updated first plurality of images, other update animations can be used. For example, in some implementations, one or more of the first plurality of images drop off the bottom of the display (or the first automatically-generated playlist affordance  592 A) and are replaced by one of more of the updated first plurality of images falling in from the top of the display (or the first automatically-generated playlist affordance  592 A). 
       FIG.  5 CP  illustrates a touch  582 P detected at a location of the first automatically-generated playlist affordance  592 A. 
       FIG.  5 CQ  illustrates the user interface  501  in response to detecting the touch  582 P at the location of the first automatically-generated playlist affordance  592 A. The user interface  501  includes an updated representation of the first automatically-generated playlist  593  that includes representations of an updated first set of media items  596 . 
     In response to detecting that the first update criterion for the first automatically-generated playlist has been met, the portable multifunctional device  100  (in addition to displaying the update animation as described above) updates the first automatically-generated playlist based on the first playlist generation criteria and user interaction with the media items in the first set of media items. Updating the first automatically-generated playlist (e.g., updating the first set of media items), includes adding one or more added media items to the first set of media items, removing one or more removed media items from the first set of media items, and maintaining a plurality of media items in the first set of media items. In some implementations, a plurality of media items in the first set of media items are maintained. 
     The user interactions with the representations of the media items can include playing various media items of the first automatically-generated playlist (e.g., multiple times), rating the media items of the first automatically-generated playlist (e.g., on a scale of 1 to 5 stars), like/dislike flagging the media items of the first automatically-generated playlist, sharing one or more of the media items of the first automatically-generated playlist, viewing related media items of the first automatically-generated playlist, viewing lyrics of the media items of the first automatically-generated playlist, or otherwise interacting with the media items. 
     For example, in some embodiments, if the user interactions with the representations of the media items include playback of one of the media items multiple times, the media item can be maintained and similar media items can be added. If the user interactions with the representations of the media items include skipping a media item (especially, repeatedly skipping a media item), the media item can be removed. If the user interactions include like (or love) flagging a media item, the media item can be maintained and similar media items can be added. Similarly, if the user interactions include dislike (or hate) flagging a media item, the media item can be removed. 
     In some embodiments, the first set of media items is updated without a user manually adding and/or removing media items from the automatically-generated playlist. In some embodiments, a user is permitted to removed media items from the automatically-generated playlist, but is not permitted to add media items to the automatically-generated playlist. However, in some embodiments, a user can add and/or remove media items from a saved version (e.g., using the save affordance. 
     In various implementations, the number of the added media items and the number of the removed media items are selected such that a size of the first automatically-generated playlist is maintained within a playlist size range. The playlist size range can be, for example, a fixed number (e.g., 80 songs in  FIG.  5 CQ ) or a range of numbers, e.g., between 75 and 90 songs. The playlist size range can be a range of a duration of playlist (e.g., a range of times) such that the amount of time to play back all the updated first set of media items is within a time window (e.g., between 3.5 and 4.5 hours). 
     In some implementations, the number of the added media items is fixed and the number of the removed media items is selected such that size of the first automatically-generated playlist is maintained within the playlist size range. In some implementations, the number of the added media items is equal to the number of the removed media items. In some implementations, the number of the added media items is greater or less than the number of the removed media items. 
     The representation of the updated first set of media items  596  includes new media item indicators  596 A displayed in association with respective added media items. Each new media item indicator  596 A can be, for example, a dot or icon displayed beside a corresponding representation of the added media item. In various implementations, the new media item indicators  596 A can be substantially similar to a new message indicator used to indicate new messages in a messaging application (e.g., a mail application) of the portable multifunctional device  100 . 
       FIG.  5 CQ  illustrates a touch  582 Q detected at a location of a representation of one of the updated first set of media items  596 . 
       FIG.  5 CR  illustrates the user interface  501  in response to detecting the touch  582 Q at the location of the representation of the one of the updated first set of media items  596 . The user interface  501  includes the playlist user interface  593  with the miniplayer user interface  550  displayed at the bottom of the display. In  FIG.  5 CR , the miniplayer user interface includes identifying text  515 A for a fifth media item (e.g., the one of the updated first set of media items). 
       FIG.  5 CR  illustrates that the new media item indicators  596 A do not include a new media item indicator for the fifth media item. Thus, in some implementations, the portable multifunctional device  100  ceases to display one of the new media item indicators in response to a user interaction with a corresponding media item. 
       FIG.  5 CR  illustrates a touch  582 R detected at a location of the share affordance  595 B. 
       FIG.  5 CS  illustrates the user interface  501  in response to a touch at the location of a share affordance of another user&#39;s device. The user interface  501  includes the playlist user interface  590 . The playlist user interface includes a shared affordance  591 B corresponding to a shared playlist from another user to the user of the portable multifunctional device  100 . In various implementations, the shared playlist includes a set of media items that is different from the first set of media items or the updated first set of media items. In some implementations, the shared playlist is fixed (and includes a date at which it was fixed). In other implementations, the shared playlist is updated when the other user&#39;s playlist is updated. 
       FIG.  5 CS  illustrates a drag  582 S detected at a location of the first automatically-generated playlist affordance  592 A. 
       FIG.  5 CT  illustrates the user interface  501  in response to detecting the drag  582 S at the location of the first automatically-generated playlist affordance  592 A. The user interface  501  continues to the display the playlist user interface  590 . In addition to the second automatically-generated playlist affordance  592 B, a third automatically-generated playlist affordance  592 C is at least partially displayed. 
     In various implementations, the multiple automatically-generated playlists are generated according to different playlist generation criteria (e.g., have different themes) and are updated according to different update criteria (e.g., on different days of the week). 
       FIGS.  6 A- 6 E  illustrate a flow diagram of a method  600  of playing back media items in accordance with some embodiments. The method  600  is performed at an electronic device (e.g., the portable multifunction device  100  in  FIG.  1 A , or the device  300  in  FIG.  3   ) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  600  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  600  provides an intuitive way to playback media items. The method reduces the cognitive burden on a user when playing back media items, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to playback media items faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 602 ), on the display, a playback status indicator regarding playback of a media item. For example, in  FIG.  5 A , the device displays a pause-play affordance  521  (in a pause state) and identifying text  511  for a first media item indicating that the first media item is playing. As another example, in  FIG.  5 C , the device displays the pause-play affordance  521  (in a play state) and the identifying text  511  for the first media item indicating that the first media item is paused. As another example, in  FIG.  5 M , the device displays the pause-play affordance  521  (in a pause sate) and identifying text  512  for a second media item indicating that the second media item is playing. As another example, in  FIG.  5 AK , the device displays a miniplayer user interface  550  including a pause-play affordance  521 A and identifying text  513 A for a third media item indicating that the third media item is playing. 
     The device displays ( 604 ), on the display, an image associated with the media item. For example, in  FIG.  5 A , the device displays an image  531  associated with the first media item. 
     The device detects ( 606 ) an input interacting with the image. In some embodiments, the device detects ( 608 ) a contact at the location of the image. The contact can be, for example, a touch or a tap at the location of the image. Thus, the image provides information to a user and also acts as an interactive affordance. This uses the space on the screen more efficiently, resulting in a more efficient human-machine interface (as a user need not manipulate the user interface to find affordances for performing the functions of interacting with the image). For battery-operated electronic devices, a more efficient human-machine user interface conserves power and increases the time between battery charges. Further, a more efficient human-machine user interface reduces the amount of user interaction with the device and reduces wear-and-tear of the device. By using less space on the screen, a smaller (and less expensive) screen can provide the same usability. For example, in  FIG.  5 B , the device detects a touch  581 A at the location of the image  531  associated with the first media item. As another example, in  FIG.  5 D , the device detects a touch  581 B at the location of the image  531  associated with the first media item. 
     In some embodiments, the device detects ( 610 ) movement of a contact over the image. The movement of the contact over the image can be, for example, a drag or a swipe. For example, in  FIG.  5 J , the device detects a horizontal leftward swipe  581 E over the image  531  associated with the first media item. As another example, in  FIG.  5 Y , the device detects a vertical upward swipe  581 J over the image  533  associated with the third media item. As another example, in  FIG.  5 AH , the device detect a vertical downward swipe  581 M over the image  533  associated with the third media item. 
     In some embodiments, the device detect ( 612 ) movement of a multi-touch contact over the image. The movement of the multi-touch contact over the image can be, for example, a multi-touch drag, a multi-touch swipe, a pinch or zoom, or a rotation. For example, in  FIG.  5 R , the device detects a vertical downward multi-touch drag  581 G over the image  533  associated with the third media item. As another example, in  FIG.  5 T , the device detects a horizontal leftward multi-touch drag  581 H over the image  533  associated with the third media item. 
     In response to a first portion of the input, the device adjusts ( 616 ) the appearance of the image on the display in accordance with the first portion of the input. By adjusting the appearance of the image on the display, additional visual information is provided to the user regarding the playback of media items. This visual information provides a more efficient human-machine interface. As noted above, a more efficient human-machine user interface conserves power and increases the time between battery charges and reduces the amount of user interaction with the device and reduces wear-and-tear of the device. In some embodiments, e.g., when the device detects movement of a contact over the image as in block  610 , the device moves ( 618 ) the image on the display in accordance with the direction of the movement of the contact. For example, in  FIG.  5 K , the device moves the image  531  associated with the first media item to the left in accordance with a leftward swipe  581 E. In some embodiments, the device starts to display ( 620 ) a second image associated with a second media item as the image is sliding off the display. For example, in  FIG.  5 L , the device displays the image  532  associated with the second media item as the image  531  associated with the first media item is sliding off the display. 
     As another example of the device moving the image in accordance with the direction of the movement of the contact, in  FIG.  5 Z , the device moves the image  533  associated with the third media item upward in accordance with an upward swipe  581 J. In some embodiments, the device displays ( 622 ) related media items, related to the media item. In some embodiments, the device displays ( 624 ) media items in a queue to be played after the media item. For example, in  FIG.  5 AA , the device displays the queue pane  543  including a queue representation  543 A that includes a plurality of elements respectively associated with one or more of the media items in the queue. In some embodiments, the device displays ( 626 ) suggested media items selected based on the media item. For example, in  FIG.  5 AB , the device displays the suggestions pane  544  including suggestion representations  544 A displaying suggested media items selected based on the third media item. In some embodiments, the device displays ( 628 ) a lyrics toggle affordance for displaying lyrics of the media item. For example, in  FIG.  5 AC , the device displays the lyrics toggle affordance  542 A. In  FIG.  5 AD , the device toggles display of the lyrics  642 B of the third media item. 
     As noted above, in response to a first portion of the input, the device adjusts ( 616 ) the appearance of the image on the display in accordance with the first portion of the input. In some embodiments, e.g., when the device detects a contact at a location of the image as in block  608 , the device changes ( 630 ) a size of the image on the display. For example, from  FIG.  5 B  to  FIG.  5 C , the device reduces the size of the image  531  associated with the first media item. As another example, from  FIG.  5 D  to  FIG.  5 E , the device increases the size of the image  531  associated with the first media item. In some embodiments, the device toggles ( 632 ) display of a border around the image (or gradually changes a virtual z height of the image and adjusts a depth effect such as a virtual shadow as the virtual z height of the image is changed). For example, from  FIG.  5 B  to  FIG.  5 C , the device ceases display of the border  531 A around the image  531  associated with the first media item. As another example, from  FIG.  5 D  to  FIG.  5 E , the device resumes displaying the borer  531 A around the image  531  associated with the first media item. 
     In some embodiments, e.g., when the device detects movement of a multi-touch contact over the image as in block  612 , the device changes ( 634 ) a shape of the image on the display (or applies a virtual tilting effect tilting the image around an axis that is parallel to the display, so that a portion of the image is higher in a virtual z direction and a portion of the image is lower in the virtual z direction when the image is tilted). In some embodiments, the device skews ( 636 ) the image on the display. For example, from  FIG.  5 R  to  FIG.  5 S , the device skews the image  533  associated with the third media item such that it appears to tilt downward. As another example, from  FIG.  5 T  to  FIG.  5 V , the device skews the image  533  associated with the third media item such that it appears to tilt rightward. In some embodiments, a magnitude of the change in the shape of the image is ( 638 ) proportional to a magnitude of the movement of the multi-touch contact. For example, in  FIG.  5 V , the magnitude of the movement of the multi-touch drag  581 H is greater than the movement of the multi-touch drag  581 H in  FIG.  5 U . Thus, the magnitude of the change in the shape of the image  533  associated with the third media item is greater in  FIG.  5 V  than in  FIG.  5 U . 
     In response to a second portion of the input, the device changes ( 640 ) playback of media items on the device in accordance with a second portion of the input. Thus, the image provides information to a user regarding a media item that is being played back and also acts as an affordance for changing the playback of the media item. This uses the space on the screen more efficiently, resulting in a more efficient human-machine interface (as a user need not manipulate the user interface to find affordances for performing the functions of interacting with the image). As noted above, a more efficient human-machine user interface conserves power and increases the time between battery charges and reduces the amount of user interaction with the device and reduces wear-and-tear of the device. In some embodiments, e.g., when the device detects movement of a contact over the image as in block  610 , the device starts playback ( 642 ) of a second media item. For example, in  FIG.  5 M , the device starts playback of the second media item, identifying by the identifying text  512  for the second media item and associated with the image  532  associated with the second media item. In some embodiments, in accordance with a determination that movement of the contact is in a first direction, the device selects ( 644 ) a prior media item in a queue as the second media item and, in accordance with a determination that the movement of the contact is in a second direction, the device selects a next media item in a queue as the second media item. For example, in  FIG.  5 M , the device starts playback of the second media item in accordance with a determination that the swipe  581 E is to the left. In some embodiments, the device starts playback of the second media item by crossfading ( 646 ) between the media item and the second media item. 
     In some embodiments, e.g., when the device detects a contact at the location of the image as in block  608 , the device pauses ( 648 ) or resumes ( 650 ) playback of the media item. For example, from  FIG.  5 B  to  FIG.  5 C , the device pauses playback of the first media item (as indicated by the change in the pause-play affordance  521 ). As another example, from  FIG.  5 D  to  FIG.  5 E , the device resumes playback of the first media item (as indicated by the change in the pause-play affordance  521 ). 
     In some embodiments, e.g., when the device detects movement of a multi-touch contact over the image as in block  612 , the device changes ( 652 ) a non-binary characteristic of the playback of the media item. For example, from  FIG.  5 R to  5 S , the device changes (decreases) the volume of the playback of the media item, as indicated by the volume affordance  524  moving from its original location  524 A. As another example, from  FIG.  5 T to  5 V , the device changes (increases) the playback time of the playback of the third media item, as indicated by the scrubbing affordance  525  moving from its original location. 
     In some embodiments, in accordance with a determination that the movement of the multi-touch contact is along a first axis, the device changes ( 654 ) a first non-binary playback characteristic and, in accordance with a determination that the movement of the multi-touch contact is along a second axis, the device changes a second non-binary playback characteristic. Thus a user can change either a first non-binary playback characteristic or a second non-binary characteristic by interacting with a single affordance. A single affordance that can perform multiple functions uses the space on the screen more efficiently, conversing power and increasing the time between battery charges, reducing the amount of user interaction with the device and corresponding wear-and-tear of the device, and providing the same usability with a smaller (and less expensive) screen. For example, in  FIG.  5 S , in accordance with a determination that the multi-touch drag  581 G is along a vertical axis, the device changes the volume of the playback of the third media item and, in  FIG.  5 U , in accordance with a determination that the multi-touch drag  581 H is along a horizontal axis, the device changes the playback time of the playback of the third media item. 
     In some embodiments, a magnitude of the change of the non-binary playback characteristic is ( 656 ) proportional to a magnitude of the movement of the multi-touch contact. For example, in  FIG.  5 V , the magnitude of the movement of the multi-touch drag  581 H is greater than the movement of the multi-touch drag  581 H in  FIG.  5 U . Thus, the magnitude of the change in the playback time of the playback of the third media item is greater in  FIG.  5 V  than in  FIG.  5 U . 
     In some embodiments, the device displays ( 658 ), on the display, a pause-play affordance. For example, in  FIG.  5 E , the device display a pause-play affordance  521  in a pause state. As another example, in  FIG.  5 G , the device displays a pause-play affordance  521  in a play state. As another example, in  FIG.  5 AK , the device display a miniplayer user interface  550  including a pause-play affordance  521 A. In some embodiments, the device detects ( 660 ) a pause-play input interacting with the pause-play affordance. For example, in  FIG.  5 F , the device detects a touch  581 C at a location of the pause-play affordance  521  while the pause-play affordance  521  is in a pause state. As another example, in  FIG.  5 H , the device detects a touch  581 D at a location of the pause-play affordance  521  while the pause-play affordance  521  in a play state. In some embodiments, in response to a first portion of the pause-play input, the device changes ( 662 ) a size of the image on the display. For example, from  FIG.  5 F  to  FIG.  5 G , the device reduces the size of the image  531  associated with the first media item. As another example, from  FIG.  5 H  to  FIG.  5 I , the device increases the size of the image  531  associated with the first media item. In some embodiments, in response to a second portion of the pause-play input, the device switches ( 664 ) between pausing and playback of the media item. For example, from  FIG.  5 F  to  FIG.  5 G , the device switches from playing back to pausing the first media item, as indicated by the play-pause affordance  521  switching from a pause state to a play state. As another example, from  FIG.  5 H  to  FIG.  5 I , the device switches from pausing to playing back the first media item, as indicated by the play-pause affordance  521  switched from a play state to a pause state. 
     In some embodiments, the device displays ( 666 ), on the display, one or more skip affordances. For example, in  FIG.  5 M , the device displays a reverse affordance  522  and a forward affordance  523 . In some embodiments, the device detects ( 668 ) a skip input interacting with one of the one or more skip affordances. For example, in  FIG.  5 N , the device detects a touch  581 F at a location of the forward affordance  523 . In some embodiments, in response to a first portion of the skip input, the device moves ( 670 ) the image on the display in accordance with one of the one or more skip affordances. By adjusting the location of the image on the display, additional visual information is provided to the user regarding the playback of media items. Further, this movement of image on the display provides an indication to the user that the image itself can be manipulated to achieve a similar effect and increases the likelihood that the user will manipulate the user interface in an efficient manner, conserving power and increases the time between battery charges and reducing wear-and-tear of the device. For example, in  FIG.  5 O  and  FIG.  5 P , the device moves the image  532  associated with the second media item to the left in accordance with detection of the touch  581 F at the location of the forward affordance  523 . As another example, the device can move the image  532  associated with the second media item to the right in accordance with detection of a touch at the location of the reverse affordance  522 . In some embodiments, in response to a second portion of the skip input, the device starts playback ( 672 ) of a second media item in accordance with the one of the one or more skip affordances. For example, in  FIG.  5 Q , the device starts playback of the third media item, as indicated by the identifying text  513  for the third media item, in accordance with detection of the touch  581 F at the location of the forward affordance  523 . As another example, the device can start playback of the first media item in accordance with detection of a touch at the location of the reverse affordance  522 . 
     In some embodiments, the device displays ( 674 ), on the display, a scrubbing affordance. For example, in  FIG.  5 W , the device displays the scrubbing affordance  525 . In some embodiments, the device detects ( 676 ) a scrubbing input interacting with the scrubbing affordance  525 . For example, in  FIG.  5 W , the device detects a drag  581 I beginning at a location of the scrubbing affordance  525 . In some embodiments, in response to a first portion of the skip input, the device reduces ( 678 ) a size of the image on the display. For example, in from  FIG.  5 W  to  FIG.  5 X , the device reduces the size of the image  533  associated with the third media item. In some embodiments, the device changes ( 680 ) display of the scrubbing affordance to a waveform indicative of the magnitude of the audio of the media item at various playback times. For example, from  FIG.  5 W  to  FIG.  5 X , the device changes display of the scrubbing affordance  525  to include a scrubbing waveform  525 B indicative of the magnitude of the audio of the third media item at various playback times. In some embodiments, the device displays ( 682 ) scrubbing speed information in a display area previous occupied by the image. For example, in  FIG.  5 X , the device displays scrubbing speed information  525 C in a display area previously occupied (e.g., in  FIG.  5 W ) by the image  533  associated with the third media item. In some embodiments, in response to a second portion of the scrubbing input, the device changes ( 684 ) a playback time of the playback of the media item. 
     In some embodiments, e.g., when the device detects movement of a contact over the image as in block  610 , in accordance with a determination that the movement of the contact over the image is in a first direction, the device displays ( 686 ) a miniplayer user interface, the miniplayer user interface including a reduced-sized version of the image and, in accordance with a determination that movement of the contact over the image is in a second direction, the device displays related media items. For example, in  FIG.  5 AI , in accordance with a determination that the swipe  581 M is in a downward direction, the device displays the miniplayer user interface  550 . The miniplayer user interface  550  includes a reduced-size version of the image  533 B associated with the third media item. And, in  FIG.  5 Z , in accordance with a determination that the swipe  581 J is in an upward direction, the device displays related media items (e.g., media items in a queue in  FIG.  5 AA  or suggested media items in  FIG.  5 AB ). 
     In some embodiments, e.g., when the device detects movement of a contact over the image as in block  610 , in accordance with a determination that movement of the contact over the image is along a first axis, the device displays ( 688 ) a miniplayer user interface, the miniplayer user interface including a reduced-sized version of the image and, in accordance with a determination that movement of the contact over the image is along a second axis, the device starts playback of a second media item. For example, in  FIG.  5 AI , in accordance with a determination that the swipe  581 M is in along a vertical axis, the device displays the miniplayer user interface  550 . The miniplayer user interface  550  includes a reduced-size version of the image  533 B associated with the third media item. And, in  FIG.  5 L , in accordance with a determination that the swipe  581 E is along a horizontal axis, the device starts playback of the second media item (as indicated in  FIG.  5 L  including identifying text  512  for the second media item). 
     In some embodiments, the device detects ( 690 ) a miniplayer input interacting with the miniplayer user interface. For example, in  FIG.  5 AL , the device detects a touch  581 N at a location of the miniplayer user interface  550 . In some embodiments, the device displays ( 692 ) a full-sized version of the image in response to detecting the miniplayer input. For example, in  FIG.  5 AP , the device displays the image  533  associated with the third media item. In some embodiments, the device displays ( 694 ) an animation temporarily including a lyrics toggle affordance in response to detecting the miniplayer input. For example,  FIGS.  5 AL- 5 AP  illustrate an animation temporarily including a lyrics toggle affordance  542 A (in  FIG.  5 AO ). 
     It should be understood that the particular order in which the operations in  FIGS.  6 A- 6 AE  have been described is merely example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods  700 ,  800 , and  900 ) are also applicable in an analogous manner to method  600  described above with respect to  FIGS.  6 A- 6 E . For example, the inputs, affordances, and user interface responses described above with reference to method  600  optionally have one or more of the characteristics of the media items, playback controls, and user interfaces described herein with reference to other methods described herein (e.g., methods  700 ,  800 , and  900 ). For brevity, these details are not repeated here. 
       FIGS.  7 A- 7 B  illustrate a flow diagram of a method  700  of queuing a media item in accordance with some embodiments. The method  700  is performed at an electronic device (e.g., the portable multifunction device  100  in  FIG.  1 A , or the device  300  in  FIG.  3   ) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  700  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  700  provides an intuitive way to queue a media item. The method reduces the cognitive burden on a user when queuing a media item, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to queue a media item faster and more efficiently conserves power and increases the time between battery charges. 
     While playing a first media item in a queue of media items, the device detects ( 702 ) a request to add a second media item to the queue. For example, in  FIG.  5 AS , the device detects a touch  581 A at the location of a queueing affordance  561 A. As another example, in  FIG.  5 BC , the device detects a touch  581 T at the location of the queuing affordance  561 A. 
     In accordance with a determination that the first media item meets group-sensitive queueing criteria, wherein the group-sensitive queuing criteria include a criterion that is met when the first media item is part of a predefined group of media items in the queue, the device provides ( 704 ) an option to add the second media item to the queue after the media items in the predefined group that are in the queue after the first media item. Thus, a user can add a media item to a queue after an album or playlist has completed without returning to interact with the device once the album or playlist has finished (or is on the final item), reducing user interaction with the device, which conserves power and increasing the time between battery charges and reduces wear-and-tear of the device. For example, in  FIG.  5 AT , the device displays a play after affordance  562 B. In  FIG.  5 AZ , the device detects a touch  581 R at a location of the play after affordance  5622 . In  FIG.  5 BA , the device displays a queue representation  543 A indicating that the selected media item is added to the queue after the rest of the media items in the playlist. 
     In some embodiments, in accordance with a determination that the first media item meets the group-sensitive queueing criteria, the device provides ( 706 ) an option to add the second media item to the queue after the first media item and before the media items in the predefined group that are in the queue after the first media item. For example, in  FIG.  5 AT , the device displays a play next affordance  562 A. In  FIG.  5 AW , the device detects a touch  581 Q at a location of the play next affordance  562 A. In  FIG.  5 AX , the device displays a queue representation  543 A indicating that the selected media item is added to the queue after the first media item and before the rest of the media items in the playlist. 
     In accordance with a determination that the first media item does not meet the group-sensitive queueing criteria, the device provides ( 708 ) an option to add the second media item to the queue after the first media item (and before the other media items in the queue). For example, in  FIG.  5 AU , the device displays a play next affordance  562 A. 
     In some embodiments, in accordance with the determination that the first media item does not meet the group-sensitive queueing criteria, the device hides ( 710 ) an option to add the second media item to the queue after the media items that are in the queue. For example, in  FIG.  5 AU , the device does not display a play after affordance  562 B (as shown in, for example,  FIG.  5 AT ). 
     In some embodiments, in accordance with the determination that the first media item does not meet the group-sensitive queueing criteria, the device provides ( 712 ) an option to add the second media item to the queue after a first plurality of media items that are in the queue and before a second plurality of media items that are in the queue. Thus, even when a playlist is large, a user can add a media item to a queue after a significant amount of time has passed without returning to interact with the device, reducing user interaction with the device, which conserves power and increasing the time between battery charges and reduces wear-and-tear of the device. For example, in  FIG.  5 AV , the device displays a play later affordance  562 C which adds the selected media item to the queue after a set number of media items (e.g., 5 media items or, in some embodiments, 20 songs), and before other media items in the queue. 
     In some embodiments, the device displays ( 714 ) a list including a plurality of elements respectively associated with one or more of the media items in the queue. For example, in  FIG.  5 AX , the device displays a queue representation  543 A with each element associated with one of the media items in the queue. As another example, in  FIG.  5 AY , the device displays the queue representation with one element associated with multiple media items in the queue (e.g., the rest of the playlist). 
     In some embodiments, each of the plurality of elements includes ( 716 ) an icon and identifying text respectively associated with the one or more of the media items in the queue. For example, in  FIG.  5 AX , the device displays a queue representation  543 A with a plurality of elements including a mini-image and identifying text indicative of respective media items. 
     In some embodiments, the plurality of elements includes ( 718 ) a first element associated with all of the other media items in the predefined group that are in the queue after the first media item and a second element associated with the second media item. For example, in  FIG.  5 AY , the device displays a queue representation  543 A with a first element associated with the rest of the playlist and a second element (above the first element) associated with the media item just added to the queue. 
     In some embodiments, the plurality of elements includes ( 720 ) a first set of elements associated with all of the other media items in the predefined group that are in the queue after the first media item and a second set of elements associated with the second media item, wherein the first set of elements and the second set of elements are visually separated on the display. For example, in  FIG.  5 AY , the device displays a queue representation  543 A with a first element associated with the rest of the playlist (e.g., a set of one element associated with all of the other media items in the predefined group that are in the queue after the first media item) and a second element associated with the media item just added to the queue (e.g., a set of one element associated with the second media item). In  FIG.  5 AY , the device displays a banner  543 B visually separating the first set of elements and the second set of elements. 
     In some embodiments, the device displays ( 722 ) the list in response to an input interacting with an image associated with the first media item. For example, in  FIG.  5 Y , the device detects a swipe  581 J over the image  533  associated with the third media item. In response, in  FIG.  5 AB , the device displays a queue representation  543 A. 
     In some embodiments, the device detects ( 724 ) an ordering input dragging one of the plurality of elements and changes an order of the media items in the queue in accordance with the ordering input. For example, in  FIG.  5 BK , the device detects a drag  581 X and, in  FIG.  5 BL , displays a queue representation  543 A in which the final media item of the queue has been moved to the top of the queue. As another example, in  FIG.  5 BM , the device detects a drag  581 X and, in  FIG.  5 BN , displays a queue representation in which the rest of the playlist is moved to the middle of the queue. 
     In some embodiments, the device detects ( 726 ) a removing input swiping one of the plurality of elements and removes one or more of the media items in the queue in accordance with the removing input. For example, in  FIG.  5 BO , the device detects a swipe  581 Z and, in  FIG.  5 BQ , displays a queue representation  543 A in which a media item associated with the swipe  581 Z has been removed from the queue. 
     In some embodiments, the device disables ( 728 ) a non-linear playback function in response to the second media item being added to the queue. Thus, a user need not manually disable any active non-linear playback functions, reducing interaction with the device, thereby conserving power and increasing the time between battery charges and reducing wear-and-tear of the device. For example, in  FIG.  5 BB , the repeat affordance  551  indicates that the repeat setting is set to an off setting and the shuffle affordance  552  indicates that the shuffle setting is set to an off setting. In some embodiments, the device enables ( 730 ) the non-linear playback function in response to the playing the second media item. For example, in  FIG.  5 BR , the repeat affordance  551  indicates that the repeat setting is set to an on setting and the shuffle affordance  552  indicates that the shuffle setting is set to an on setting. 
     It should be understood that the particular order in which the operations in  FIGS.  7 A- 7 B  have been described is merely example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods  700 ,  900 , and  1000 ) are also applicable in an analogous manner to method  700  described above with respect to  FIGS.  7 A- 7 B . For example, the inputs, affordances, and user interface responses described above with reference to method  700  optionally have one or more of the characteristics of the media items, playback controls, and user interfaces described herein with reference to other methods described herein (e.g., methods  700 ,  900 , and  1000 ). For brevity, these details are not repeated here. 
       FIGS.  8 A- 8 D  illustrate a flow diagram of a method  800  of managing storage of media items in accordance with some embodiments. The method  800  is performed at an electronic device (e.g., the portable multifunction device  100  in  FIG.  1 A , or the device  300  in  FIG.  3   ) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  800  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  800  provides an intuitive way to managing storage of media items. The method reduces the cognitive burden on a user when managing storage of media items, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to manage storage of media items faster and more efficiently conserves power and increases the time between battery charges. 
     While a plurality of media items are stored on the device, the device detects ( 802 ) the occurrence of a condition that corresponds to a request to free storage on the device, wherein the plurality of media items uses a first amount of storage on the device and a minimum amount of storage on the device has been reserved for media items. Thus, a user can reduce the amount of storage of the device used by media items while retaining at least a threshold amount of media items on the device. With less data stored on the storage device, memory reads are faster and more storage is available for use as virtual processor cache, speeding up other operations. Further, by storing less data at the storage location, fewer or smaller (and less expensive) storage devices of the device (e.g., within the device, coupled to the device, or at a cloud storage facility) are needed by the user. In some embodiments, the device detects the occurrence of the condition when the device receives ( 804 ) a request to store an additional one or more media items on the device, wherein the additional one or more media items would user a second amount of storage on the device, and the device determines that the second amount of storage is greater than an available amount of storage on the device. For example, in  FIG.  5 BT , the device detects a touch  582 C at a location of a download affordance  571 B for downloading an album and determines that the amount of available storage is less than the size of the album, as shown by the insufficient storage window  564  in  FIG.  5 BW . In some embodiments, the device detects the occurrence of the condition when the device detects ( 806 ) an input interacting with a displayed increase free space affordance. For example, in  FIG.  5 BW , the device detects a touch  582 J at a location of an optimize storage affordance  564 A. 
     In accordance with a determination that the first amount of storage on the device is greater than the minimum amount of storage on the device that has been reserved for media items, the device deletes ( 808 ) one or more of the plurality of media items. For example, in  FIG.  5 CB , the device displays a media deletion warning  575 C indicating that files may be deleted. Accordingly, a user is warned that media items may be deleted before they are removed from the device, reducing the likelihood that a user would need to add media items back the device with additional interaction with the device. Reducing interaction with the device conserves and increases the time between battery charges and reduces wear-and-tear of the device. 
     In accordance with a determination that the first amount of storage on the device is less than the minimum amount of storage on the device that has been reserved for media items, the device forgoes deleting ( 810 ) one or more of the plurality of media items. 
     In some embodiments, the device displays ( 812 ), on the display, an optimize storage affordance. For example, in  FIG.  5 BW , the device displays the optimize storage affordance  564 A. As another example, in  FIG.  5 BY , the device displays an optimize storage feature toggle  576 A. In some embodiments, the device detects ( 814 ) an input interacting with an optimization affordance displayed in a settings menu. For example, in  FIG.  5 BY , the device detects a touch  582 F at a location of the optimize storage feature toggle  576 A. In some embodiments, the device detects ( 816 ) an input interacting with an optimization affordance displayed in a storage full notification. For example, in  FIG.  5 BW , the device detects a touch  582 J at a location of the optimize storage affordance  564 A. 
     In some embodiments, in response to detecting an input interacting with the optimize storage affordance, the device displays ( 818 ), on the display, a plurality of minimum media storage option affordances corresponding to a plurality of minimum media storage values. For example, in  FIG.  5 BZ , the device displays a plurality of media storage reservation size affordances  576 C. In some embodiments, the plurality of minimum media storage values are ( 820 ) based on a total amount of storage on the device. Accordingly, a user is provided with options that are based the storage device reducing interaction with the device, thereby conserving power and increasing the time between battery charges and reducing wear-and-tear of the device. For example, in  FIG.  5 BZ , the plurality of media storage reservation size affordances  576 C are associated with no minimum, 1 GB, 2 GB, and 4 GB based on a total amount of storage on the device of 32 GB. 
     In some embodiments, in response to an input interacting with a particular one of the minimum media storage option affordances corresponding to a particular one of the minimum media storage values, the device sets ( 822 ) the minimum amount of storage on the device that has been reserved for media items to the particular one of the minimum media storage values. For example, in  FIG.  5 BZ , the device detects a touch  582 G at a location of a media storage reservation size affordance  576 C associated with 2 GB and sets the minimum amount of storage on the device that has been reserved for media items to 2 GB, as indicated in  FIG.  5 CA . 
     In some embodiments, the device determines ( 824 ) that the minimum amount of storage on the device that has been reserved for media items is less than a current amount of storage on the device used by media files and, in response, displays ( 826 ), on the display, a notification indicating the current amount of storage on the device used by media files. For example, in  FIG.  5 CB , the device displays a media deletion warning  575 C indicating the current amount of storage on the device used by media files (e.g., 6.4 GB) and that the minimum amount of storage on the device that has been reserved for media items is less than that amount. 
     In some embodiments, the device determines ( 828 ) that the minimum amount of storage on the device that has been reserved for media items is greater than a current amount of storage on the device used by media files and, in response, forgoes displaying ( 830 ), on the display, a notification indicating the current amount of storage on the device used by media files. 
     In some embodiments, the device displays ( 832 ), on the display, a manual storage management affordance. For example, in  FIG.  5 CD , the device displays a manual storage management affordance  564 B in an insufficient storage window  564 . 
     In some embodiments, in response to an input interacting with the manual storage management affordance, the device displays ( 834 ), on the display, a manual storage management user interface including a list of media item data regarding a plurality of media items and a delete affordance for deleting one or more of the plurality of media items. Thus, a user can quickly delete media items, increasing the amount of free storage at the storage location. With less data stored on the storage device, memory reads are faster and more storage is available for use as virtual processor cache, speeding up other operations. Further, by storing less data at the storage location, fewer or smaller (and less expensive) storage devices of the device (e.g., within the device, coupled to the device, or at a cloud storage facility) are needed by the user. For example, in  FIG.  5 CD , the device detects a touch  582 J at a location of the manual storage management affordance  564 B. In  FIG.  5 CE , the device displays a manual storage management user interface  577  including a list of media items  577 F and a delete selected affordance  577 A. 
     In some embodiments, a set of the plurality of media items corresponding to an album are ( 836 ) listed together. For example, in  FIG.  5 CE , the list of media items  577 F includes three sets of media items corresponding to three albums listed in three groupings. 
     In some embodiments, the plurality of media items are prioritized according to size of the media items and/or listening history. Thus, a user can quickly identify non-prioritized media items that user a large amount of storage and delete them, increasing the amount of free storage of the device. For example, in  FIG.  5 CE , the media items may be filtered to include only media items that are being proposed for deletion in the list of media items  577 F or the list of media items  577 F an ordered list of items that includes all media items, with the proposed media items for deletion sorted to the top. 
     In some embodiments, the manual storage management user interface includes a selection affordance for selecting or deselecting one or more of the plurality of media items. For example, in  FIG.  5 CE , the manual storage management user interface  577  includes a plurality of selection affordances  577 E for selecting and deselecting individual media items. As another example, in  FIG.  5 CE , the manual storage management user interface  577  includes a deselect all affordance  577 B for deselecting the selected media items. In some embodiments, the deselect all affordance  577 B is replaced with a select all affordance when no media items are selected. 
     In some embodiments, in response to an input interacting with an add affordance for adding one or more media items to a library, the device displays ( 844 ), on the display, an auto-add affordance for storing media items in the library on the device. For example, in  FIG.  5 BR , the device detects a touch  582 A at a location of an add affordance  571 A. In response, in  FIG.  5 BS , the device displays an auto-add window  563  including an activate affordance  563 A for activating the auto-add feature. In some embodiments, the one or more media items are ( 846 ) displayed with a location region, the location region including the add affordance when the media items are not in the library, the location region including a download affordance when the media items are in the library but not stored on the device, and the location region being empty when the media items are stored on the device. For example, in  FIG.  5 BR , the device displays a location region including the add affordance  571 A. In  FIG.  5 BT , the device displays a download affordance  571 B in the location region, and in  FIG.  5 BV , the track download indicators  547 E are absent for downloaded tracks. In various implementations, when the album is completed downloading, the download indicator affordance  571 C is replaced by a whitespace. 
     In some embodiments, the device displays ( 848 ), on the display, a list of playlist selection affordances for synching a set of media items with the device, the list of playlist selection affordances including a smart playlist selection affordance for synching an algorithmically selected set of media items, a random playlist selection affordance for synching a random set of media items with the user device, and a user playlist selection affordances for synching a user-selected set of media items. For example, in  FIG.  5 CF , the device displays a synched playlist user interface  578  including a smart playlist selection affordance  578 B, a random playlist selection affordance  578 C, and a user playlist selection affordance  578 D in a group of such user playlist selection affordances. In some embodiments, the device detects ( 850 ) an input interacting with the user playlist selection affordance. For example, in  FIG.  5 CF , the device detects a touch  582 K at a location of the user playlist selection affordance  578 D. In some embodiments, in accordance with a determination that a size of the user-selected set of media items is greater than an amount of available storage on the device, the device displays ( 852 ) a notification indicating that at least some of the user-selected set of media items will not be stored on the device. For example, in  FIG.  5 CG , the device displays a large playlist window  565  indicating that only 350 out of 500 songs will be synched. As another example, in  FIG.  5 CI , the device displays a synched playlist selection affordance  579 A that indicates that large playlist is selected for synching and that the large playlist is only partially synched. 
     It should be understood that the particular order in which the operations in  FIGS.  8 A- 8 D  have been described is merely example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods  600 ,  700 , and  900 ) are also applicable in an analogous manner to method  800  described above with respect to  FIGS.  8 A- 8 D . For example, the media items, playback controls, and user interfaces described above with reference to method  800  optionally have one or more of the characteristics of the inputs, affordances, and user interface responses described herein with reference to other methods described herein (e.g., methods  600 ,  700 , and  900 ). For brevity, these details are not repeated here. 
       FIGS.  9 A- 9 E  illustrate a flow diagram of a method  900  of updating a playlist in accordance with some embodiments. The method  900  is performed at an electronic device (e.g., the portable multifunction device  100  in  FIG.  1 A , or the device  300  in  FIG.  3   ) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  900  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  900  provides an intuitive way to update a playlist. The method reduces the cognitive burden on a user when updating a playlist, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to update a playlist faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 902 ), on the display, a representation of a first automatically-generated playlist, the representation of the first automatically-generated playlist including representations of a first set of media items selected for inclusion in the first automatically-generated playlist based on first playlist generation criteria for the first automatically-generated playlist. For example, in  FIG.  5 CK , the device displays a representation of the first automatically-generated playlist  593 . The representation of the first automatically-generated playlist  593  includes representations of a first set of media items  596  selected for including based on first playlist generation criteria. In the example of  FIG.  5 CK , the first set of media items are selected based on an oldies theme, as indicated by the identifying information  594 . 
     In some embodiments, the device displays ( 904 ) a save affordance for saving the first set of media items as a non-updated playlist. For example, in  FIG.  5 CK , displays a save affordance  595 A. The device detects a touch  528 O at a location of the save affordance  595 A and, in response, saves the first set of media items as a non-updated playlist, as indicated in  FIG.  5 CL  by the inclusion of a saved affordance  591 A in the plurality of playlist affordances  591 . 
     In some embodiments, the device displays ( 906 ) a share affordance for sharing the first set of media items with another device as a shared playlist. For example, in  FIG.  5 CR , the device displays a share affordance  595 B. In  FIG.  5 CS , the device includes a shared affordance  591 B in the plurality of playlist affordances  591  indicating that another device has shared a playlist with the device. In some embodiments, in response to a first update criterion being met (as described further below), the device updates ( 908 ) the first set of media items of the shared playlist. In some embodiments, the device does not update the shared playlist and the playlist is a non-updated playlist. 
     While displaying the representation of the first automatically-generated playlist, the device detects ( 910 ) user interaction with the representations of the first set of media items. For example, in  FIG.  5 CQ , the device detects a touch  582 Q at a location of a representation of one of the first set of media items  596 . In some embodiments, in response to detecting user interaction with a representation of one of the first set of media items, the device starts playback ( 912 ) of the one of the first set of media items. For example, in  FIG.  5 CQ , the device detects a touch  582 Q at a location of a representation of one of the first set of media items  596  and, in response, begins playback of the media item, as illustrated in  FIG.  5 CR , by the display of identifying text  515 A and the pause-play affordance  521 A in the pause state. 
     The device detects ( 914 ) that a first update criterion for the first automatically-generated playlist has been met. In some embodiments, the first update criterion specifies ( 916 ) that the first set of media items is to be updated on predefined day of the week. For example, in  FIG.  5 CK , the identifying information  594  indicates that the playlist was updated last Thursday. In  FIG.  5 CQ , the identifying information  595  indicates that the playlist was updated today (e.g., Thursday). In various implementations, the first update criterion is met for a plurality of users with similarly themed playlists. For example, all users may have a “new releases” playlist updated every Monday. 
     The device updates ( 918 ) the first set of media items based on the first playlist generation criteria and the user interaction with the representations of the first set of media items by adding one or more added media items to the first set of media items, removing one or more removed media items from the first set of media items, and maintaining a plurality of maintained media items in the first set of media items. Thus, a user is periodically automatically presented with a new set of media items for consumption, reducing interaction with the device as the user searches for new media items. Reducing interaction with the device conserves power and increases the time between battery charges and, also, reduces wear-and-tear of the device. For example, from  FIG.  5 CK  to  FIG.  5 CQ , a number of media items have been added, removed, and maintained. 
     In some embodiments, the added media items are selected ( 920 ) based on user-agnostic criteria and user-specific criteria. For example, the added media items can be based on the theme (e.g., oldies), a user-agnostic criteria and user interaction with the playlist, a user-specific criteria. Thus, a user is periodically automatically presented with a new set of media items for consumption based on user preferences, reducing interaction with the device as the user searches for new media items based on their preferences. As mentioned above, reducing interaction with the device conserves power and increases the time between battery charges and, also, reduces wear-and-tear of the device. 
     In some embodiments, the removed media items are selected ( 922 ) based on user-specific criteria. For example, the removed media items can be based on user interaction with the playlist or an amount of a time the media item has been maintained on the user playlist. 
     In some embodiments, the maintained media items include ( 924 ) a majority of the first set of media items. For example, in  FIG.  5 CQ , of the nine displayed media items, six are maintained from the playlist in  FIG.  5 CK . 
     In some embodiments, a number of the added media items and a number of removed media items are selected ( 926 ) such that a size of the first automatically-generated playlist is maintained within a playlist size range. Maintaining the size of the playlist within a manageable size range increases the likelihood that a user will interact with the automatically-generated playlist, reducing interaction with the device as the user need not alternatively search for new media items. Reducing interaction with the device conserves power and increases the time between battery charges and, also, reduces wear-and-tear of the device. For example, in  FIG.  5 CQ , the identifying information  594  indicates that there are 80 songs on the playlist. In some embodiments, the playlist size range is ( 928 ) a range of a number of media items. For example, the range may be between 75 and 85 songs. In some embodiments, the playlist size range is ( 930 ) a range of duration time. For example, the range may be between 3.5 and 4.5 hours. 
     The device displays ( 932 ), on the display, an updated representation of the first automatically-generated playlist that includes representations of the updated first set of media items. For example, in  FIG.  5 CQ , the device displays representations of the updated set of media items  596 . In some embodiments, the device displays ( 934 ), on the display, one or more new media item indicators displayed in respective association with one or more representations of the added media items. In some embodiments, each new media item indicator includes ( 936 ) a dot or icon displayed beside a respective representation of an added media item. Thus, a user can easily identify new media items for consumption, reducing interaction with the device as the user searches for new media items. Reducing interaction with the device conserves power and increases the time between battery charges and, also, reduces wear-and-tear of the device. For example, in  FIG.  5 CQ , the device displays new media item indicators  596 A as a dot beside representations of added media items. In some embodiments, each new media item indicator is ( 938 ) substantially similar to a new message indicator used to indicate new messages in a messaging application of the device. In some embodiments, in response an input interacting with one of the representations of the added media items, the device ceases display ( 940 ) of a corresponding one of the one or more new media item indicators. For example, in response to detecting the touch  582 Q at the representation of the fifth media item, the device ceases display, in  FIG.  5 CR , or the corresponding new media item indicator  596 A. 
     In some embodiments, the device displays ( 942 ), on the display, a first playlist affordance for displaying the representation of the first automatically-generated playlist, the first playlist affordance including a first plurality of images respectively associated with a plurality of the first set of media items. For example, in  FIG.  5 CJ , the device displays the first automatically-generated playlist affordance  592 A and, in response to detecting a touch  582 N at the location of the first automatically-generated playlist affordance  592 A, displays, as illustrated in  FIG.  5 CK , the representation of the first automatically-generated playlist  593 . The first automatically-generated playlist affordance  592 A (shown in  FIG.  5 CJ ) includes a plurality of images respectively associated with a plurality of the first set of media items (shown in  FIG.  5 CK ). 
     In some embodiments, the device displays ( 944 ), on the display, an updated first playlist affordance for displaying the updated representation of the first automatically-generated playlist, the updated first playlist affordance including an updated first plurality of images respectively associated with a plurality of the updated first set of media items. Thus, a user is notified that a new set of media items is available for consumption, reducing interaction with the device as the user searches for new media items. Reducing interaction with the device conserves power and increases the time between battery charges and, also, reduces wear-and-tear of the device. For example, in  FIG.  5 CP , the device displays the updated first automatically-generated playlist affordance  592 A and, in response to detecting a touch  582 P at the location of the updated first automatically-generated playlist affordance  592 A, displays, as illustrated in  FIG.  5 CQ , the updated representation of the first automatically-generated playlist  593 . The updated automatically-generated playlist affordance  592 A (shown in  FIG.  5 CP ) includes an updated plurality of images respectively associated with a plurality of the updated first set of media items (shown in  FIG.  5 CQ ). In some embodiments, the device displays ( 946 ), on the display, an update animation in which one or more of the first plurality of images are replaced with one or more of the updated first plurality of images. For example, from  FIGS.  5 CL- 5 CP , an update animation is illustrated in which one or more of the first plurality of images are replaced with one or more of the updated first plurality of images. 
     In some embodiments, the device displays ( 948 ), on the display, a representation of a second automatically-generated playlist, the representation of the second automatically-generated playlist including representations of a second set of media items selected for inclusion in the second automatically-generated playlist based on second playlist generation criteria for the second automatically-generated playlist. For example, in  FIG.  5 CT , the device displays a second automatically-generated playlist affordance  592 B for displaying a representation of a second automatically-generated playlist. 
     In some embodiments, the second playlist generation criteria is ( 950 ) different from the first playlist generation criteria. In some embodiments, the first playlist generation criterion is ( 952 ) a first theme selected from a theme set including new releases, older songs, or user favorites and the second playlist generation criterion is selected from the theme set. Thus, a user is notified that with a new set of media items of a theme are available for consumption, reducing interaction with the device as the user searches for new media items of the theme. Reducing interaction with the device conserves power and increases the time between battery charges and, also, reduces wear-and-tear of the device. For example, in  FIG.  5 CS , the device displays the first automatically-generated playlist affordance  592 A with a designation of an oldies theme and, in  FIG.  5 CT , the device displays the second automatically-generated playlist affordance  592 B with a designation of a new releases theme. In some embodiments, the device provides ( 954 ) an option to select the first playlist generation criteria and the second playlist generation criteria (e.g., a setting for a user to select the theme for one or more of the playlists). 
     In some embodiments, while displaying the representation of the second automatically-generated playlist, the device detects ( 956 ) user interaction with the representations of the second set of media items. 
     In some embodiments, the device detects ( 958 ) that a second update criterion for the second automatically-generated playlist has been met. In some embodiments, the second update criterion is ( 960 ) different from the first update criterion. In some embodiments, the first update criterion specifies ( 962 ) that the first automatically-generated playlist is to be updated on a first day of the week and the second update criterion specifies that the second playlist is to be updated on a second day of the week that is different from the first day of the week. Thus, a user is presented with a new set of media items for consumption meeting different themes on different days, increasing the likelihood that a user will interact with the automatically selected new set of media items, reducing interaction with the device as the user searches for new media items. Reducing interaction with the device conserves power and increases the time between battery charges and, also, reduces wear-and-tear of the device. For example, in  FIG.  5 CK , the identifying information  594  indicates that the playlist was updated last Thursday. In  FIG.  5 CQ , the identifying information  595  indicates that the playlist was updated today (e.g., Thursday). The second playlist can be updated on a different day of the week, e.g., Tuesday. 
     In some embodiments, the device updates ( 964 ) the second set of media items based on the second playlist generation criteria and the user interaction with the representations of the second set of media items. In some embodiments, a number of media items added to the second set of media items is ( 966 ) different from a number of the added media items added to the first set of media items. For example, whereas  FIG.  5 CQ  illustrates that the updated first set of media items includes three added media items (out of nine illustrated), an updated second set of media items can include more than three (out of nine) added media items. 
     In some embodiments, the device displays ( 968 ), on the display, an updated representation of the second automatically-generated playlist, the updated representation of the second automatically-generated playlist including representations of the updated second set of media items. 
     In some embodiments, the first automatically-generated playlist is ( 970 ) one of seven automatically-generated playlists with seven different playlist generation criteria and seven different update criteria specifying that the respective automatically-generated playlist is to be updated on a respective day of the week. For example, in  FIG.  5 CS , the device displays a first automatically-generated playlist affordance  562 A and partially displays a second automatically-generated playlist affordance  562 B. In  FIG.  5 CT , the device displays the second automatically-generated playlist affordance  562 B and partially displays a third automatically-generated playlist affordance  562 C. In some embodiments, further scrolling reveals four additional automatically-generated playlist affordances. 
     It should be understood that the particular order in which the operations in  FIGS.  9 A- 9 E  have been described is merely example and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods  600 ,  700 , and  800 ) are also applicable in an analogous manner to method  900  described above with respect to  FIGS.  9 A- 9 E . For example, the media items, playback controls, and user interfaces described above with reference to method  900  optionally have one or more of the characteristics of the inputs, affordances, and user interface responses described herein with reference to other methods described herein (e.g., methods  60 ,  700 , and  800 ). For brevity, these details are not repeated here.

In some embodiments, the processing unit  1010  is configured to start to display (e.g., with the display control unit  1012 ) a second image associated with a second media item as the image is sliding off of the display unit  1002 . In some embodiments, the processing unit  1010  is configured to display (e.g., with the display control unit  1012 ) related media items. In some embodiments, the processing device  1010  is configured to display (e.g., with the display control unit  1012 ) media items in a queue to be played after the media item. In some embodiments, the processing device  1010  is configured to display (e.g., with the display control unit  1012 ) suggested media items selected based on the media item. In some embodiments, the processing device  1010  is configured to display (e.g., with the display control unit  1012 ) a lyrics toggle affordance for toggling display of lyrics of the media item. 
     In some embodiments, such as embodiments in which the processing unit  1010  detects a contact at a location of the image, the processing device  1010  is configured to change (e.g., with the display control unit  1012 ) a size of the image on the display unit  1002 . In some embodiments, the processing device  1010  is configured to toggle display (e.g., with the display control unit  1012 ) of a border around the image. 
     In some embodiments, such as embodiments in which the processing unit  1010  detects movement of a multi-touch contact over the image, the processing device  1010  is configured to change (e.g., with the display control unit  1012 ) a shape of the image on the display unit  1002 . In some embodiments, the processing device  1010  is configured to skew (e.g., with the display control unit  1012 ) the image. In some embodiments, a magnitude of the change in the shape of the image is proportional to a magnitude of the movement of the multi-touch contact. 
     The processing device  1010  is configured to, in response to a second portion of the input, change playback (e.g., with the playback control unit  1016 ) of media items on the device in accordance with the second portion of the input. In some embodiments, such as embodiments in which the processing device  1010  detects movement of a contact over the image, the processing device  1010  is configured to start playback (e.g., with the playback control unit  1016 ) of a second media item. In some embodiments, the processing device  1010  is configured to, in accordance with a determination that movement of the contact is in a first direction, select (e.g., with the playback control unit  1016 ) a prior media item in a queue as the second media item and, in accordance with a determination that the movement of the contact is in a second direction, select (e.g., with the playback control unit  1016 ) a next media item in a queue as the second media item. In some embodiments, the processing device  1010  crossfades (e.g., with the playback control unit  1016 ) between the media item and the second media item. 
     In some embodiments, such as embodiments in which the processing device  1010  detects a contact at a location of the image, the processing device  1010  is configured to pause playback (e.g., with the playback control unit  1016 ) of the media item. In some embodiments, the processing device  1010  is configured to resume playback (e.g., with the playback control unit  1016 ) of the media item.

     In some embodiments, the processing device  1310  is configured to display (e.g., with the display control unit  1312 ), on the display unit  1302 , a representation of a second automatically-generated playlist, the representation of the second automatically-generated playlist including representations of a second set of media items selected for inclusion in the second automatically-generated playlist based on second playlist generation criteria for the second automatically-generated playlist. In some embodiments, the second playlist generation criteria is different from the first playlist generation criteria. In some embodiments, the first playlist generation criterion is a first theme selected from a theme set including new releases, older songs, or user favorites and the second playlist generation criterion is selected from the theme set. In some embodiments, the processing device  1310  is configured to provide an option (e.g., with the display control unit  1312 ) to select the first playlist generation criteria and the second playlist generation criteria. 
     In some embodiments, the processing device  1310  is configured to, while displaying the representation of the second automatically-generated playlist, detect (e.g., with the input detecting unit  1314 ) user interaction with the representations of the second set of media items. 
     In some embodiments, the processing device  1310  is configured to detect (e.g., with the playlist updating unit  1316 ) that a second update criterion for the second automatically-generated playlist has been met. In some embodiments, the second update criterion is different from the first update criterion. In some embodiments, the first update criterion specifies that the first automatically-generated playlist is to be updated on a first day of the week and the second update criterion specifies that the second playlist is to be updated on a second day of the week that is different from the first day of the week. 
     In some embodiments, the processing device  1310  is configured to update e.g., with the playlist updating unit  1316 ) the second set of media items based on the second playlist generation criteria and the user interaction with the representations of the second set of media items. In some embodiments, a number of media items added to the second set of media items is different from a number of the added media items added to the first set of media items. 
     In some embodiments, the processing device  1310  is configured to display (e.g., with the display control unit  1312 ), on the display unit  1302 , an updated representation of the second automatically-generated playlist, the updated representation of the second automatically-generated playlist including representations of the updated second set of media items. 
     In some embodiments, the first automatically-generated playlist is one of seven automatically-generated playlists with seven different playlist generation criteria and seven different update criteria specifying that the respective automatically-generated playlist is to be updated on a respective day of the week. 
     The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to  FIGS.  1 A and  13   ) or application specific chips. 
     The operations described above with reference to  FIGS.  9 A- 9 E  are, optionally, implemented by components depicted in  FIGS.  1 A- 1 B  or  FIG.  13   . For example, displaying operation  902 , detecting operation  910 , detecting operation  914 , updating operation  918 , and displaying operation  932  are, optionally, implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  optionally uses or calls data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS.  1 A- 1 B . 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best use the invention and various described embodiments with various modifications as are suited to the particular use contemplated.
