Title: Systems and methods for interleaving recommended media items in a playlist

Description:
PRIORITY APPLICATION(S) 
     This application claims priority to U.S. Prov. App. No. 63/273,783, filed Oct. 29, 2021, which is hereby incorporated by reference in its entirety. 
    
    
     TECHNICAL FIELD 
     The disclosed embodiments relate generally to media provider systems, and, in particular, to temporarily interleaving recommended media items in a user-curated playlist, while the user has turned on a recommendation setting for the playlist, without changing the original media included in the playlist. 
     BACKGROUND 
     Recent years have shown a remarkable growth in consumption of digital goods such as digital music, movies, books, and podcasts, among many others. The overwhelmingly large number of these goods often makes navigation and discovery of new digital goods an extremely difficult task. To cope with the constantly growing complexity of navigating the large number of goods, users create and select playlists to easily organize and access media items, including playlists curated by the users themselves and playlists curated by other parties, such as content providers. 
     SUMMARY 
     While a user can typically select a curated playlist that includes automatically recommended media content, users often consume playlists that they have curated themselves or that have been curated by other users (e.g., friends of the user). Playlists that users have curated themselves represent the users&#39; own taste profile for digital content, and can often evoke an emotional or nostalgic response for the user. Sometimes, user-curated playlists are associated with a particular event, time, or memory (e.g., a user&#39;s wedding playlist), that the user would like to maintain without modification. Such playlists may have been curated by the user&#39;s friends, or together with the user&#39;s friends. However, when the user selects a user-curated playlist for playback, the user is limited to the content the user added to the playlist and is prevented from discovering new content that is not already in the playlist. 
     In the disclosed embodiments, systems and methods are provided for presenting the user with recommendations that are interleaved within a playlist that was curated by the user or other users (e.g., friends of the user). The user is enabled to toggle the recommendations on and off within a same user interface in which the user views the playlist (e.g., a user interface that includes representations of media items in the playlist). Thus, the user can easily switch between viewing only the media items in the user&#39;s original user-curated playlist, and viewing additional recommended media items interleaved with the media items in the user&#39;s original playlist, without affecting the user&#39;s stored original user-curated playlist. In this way, the user is able to maintain the user&#39;s original playlist without modification while still being presented with recommended media content. 
     To that end, in accordance with some embodiments, a method is provided. The method includes providing, to a user, a user-curated playlist, the user-curated playlist including an ordered set of media items that were added by the user. The method further includes, while providing a first media item in the ordered set of media items, receiving a first user input selecting an option to include recommended media items in the user-curated playlist. The method includes, in response to the first user input, updating the user-curated playlist to include a first recommended media item, the first recommended media item selected without user intervention based at least in part on attributes of the user-curated playlist. The first recommended media item is positioned in the user-curated playlist in between media items that were added to the ordered set of media items by the user. 
     In accordance with some embodiments, a computer system is provided. The computer system includes one or more processors and memory storing one or more programs. The one or more programs include instructions for performing any of the methods described herein. 
     In accordance with some embodiments, a non-transitory computer-readable storage medium is provided. The non-transitory computer-readable storage medium stores one or more programs for execution by a computer system with one or more processors. The one or more programs comprising instructions for performing any of the methods described herein. 
     Thus, systems are provided with improved methods for enhancing a user-curated playlist.

       FIG.  1    is a block diagram illustrating a media content delivery system  100 , in accordance with some embodiments. The media content delivery system  100  includes one or more electronic devices  102  (e.g., electronic device  102 - 1  to electronic device  102 - m,  where m is an integer greater than one), one or more media content servers  104 , and/or one or more content distribution networks (CDNs)  106 . The one or more media content servers  104  are associated with (e.g., at least partially compose) a media-providing service. The one or more CDNs  106  store and/or provide one or more content items (e.g., to electronic devices  102 ). In some embodiments, the CDNs  106  are included in the media content servers  104 . One or more networks  112  communicably couple the components of the media content delivery system  100 . In some embodiments, the one or more networks  112  include public communication networks, private communication networks, or a combination of both public and private communication networks. For example, the one or more networks  112  can be any network (or combination of networks) such as the Internet, other wide area networks (WAN), local area networks (LAN), virtual private networks (VPN), metropolitan area networks (MAN), peer-to-peer networks, and/or ad-hoc connections. 
     In some embodiments, an electronic device  102  is associated with one or more users. In some embodiments, an electronic device  102  is a personal computer, mobile electronic device, wearable computing device, laptop computer, tablet computer, mobile phone, feature phone, smart phone, an infotainment system, digital media player, a speaker, television (TV), digital versatile disk (DVD) player, and/or any other electronic device capable of presenting media content (e.g., controlling playback of media items, such as music tracks, podcasts, videos, etc.). Electronic devices  102  may connect to each other wirelessly and/or through a wired connection (e.g., directly through an interface, such as an HDMI interface). In some embodiments, electronic devices  102 - 1  and  102 - m  are the same type of device (e.g., electronic device  102 - 1  and electronic device  102 - m  are both speakers). Alternatively, electronic device  102 - 1  and electronic device  102 - m  include two or more different types of devices. 
     In some embodiments, electronic devices  102 - 1  and  102 - m  send and receive media-control information through network(s)  112 . For example, electronic devices  102 - 1  and  102 - m  send media control requests (e.g., requests to play music, podcasts, movies, videos, or other media items, or playlists thereof) to media content server  104  through network(s)  112 . Additionally, electronic devices  102 - 1  and  102 - m,  in some embodiments, also send indications of media content items to media content server  104  through network(s)  112 . In some embodiments, the media content items are uploaded to electronic devices  102 - 1  and  102 - m  before the electronic devices forward the media content items to media content server  104 . 
     In some embodiments, electronic device  102 - 1  communicates directly with electronic device  102 - m  (e.g., as illustrated by the dotted-line arrow), or any other electronic device  102 . As illustrated in  FIG.  1   , electronic device  102 - 1  is able to communicate directly (e.g., through a wired connection and/or through a short-range wireless signal, such as those associated with personal-area-network (e.g., BLUETOOTH/BLE) communication technologies, radio-frequency-based near-field communication technologies, infrared communication technologies, etc.) with electronic device  102 - m.  In some embodiments, electronic device  102 - 1  communicates with electronic device  102 - m  through network(s)  112 . In some embodiments, electronic device  102 - 1  uses the direct connection with electronic device  102 - m  to stream content (e.g., data for media items) for playback on the electronic device  102 - m.    
     In some embodiments, electronic device  102 - 1  and/or electronic device  102 - m  include a media application  222  ( FIG.  2   ) that allows a respective user of the respective electronic device to upload (e.g., to media content server  104 ), browse, request (e.g., for playback at the electronic device  102 ), and/or present media content (e.g., control playback of music tracks, playlists, videos, etc.). In some embodiments, one or more media content items are stored locally by an electronic device  102  (e.g., in memory  212  of the electronic device  102 ,  FIG.  2   ). In some embodiments, one or more media content items are received by an electronic device  102  in a data stream (e.g., from the CDN  106  and/or from the media content server  104 ). The electronic device(s)  102  are capable of receiving media content (e.g., from the CDN  106 ) and presenting the received media content. For example, electronic device  102 - 1  may be a component of a network-connected audio/video system (e.g., a home entertainment system, a radio/alarm clock with a digital display, or an infotainment system of a vehicle). In some embodiments, the CDN  106  sends media content to the electronic device(s)  102 . 
     In some embodiments, the CDN  106  stores and provides media content (e.g., media content requested by the media application  222  of electronic device  102 ) to electronic device  102  via the network(s)  112 . Content (also referred to herein as “media items,” “media content items,” and “content items”) is received, stored, and/or served by the CDN  106 . In some embodiments, content includes audio (e.g., music, spoken word, podcasts, audiobooks, etc.), video (e.g., short-form videos, music videos, television shows, movies, clips, previews, etc.), text (e.g., articles, blog posts, emails, etc.), image data (e.g., image files, photographs, drawings, renderings, etc.), games (e.g., 2- or 3-dimensional graphics-based computer games, etc.), or any combination of content types (e.g., web pages that include any combination of the foregoing types of content or other content not explicitly listed). In some embodiments, content includes one or more audio media items (also referred to herein as “audio items,” “tracks,” and/or “audio tracks”). 
     In some embodiments, media content server  104  receives media requests (e.g., commands) from electronic devices  102 . In some embodiments, media content server  104  includes a voice API, a connect API, and/or key service. In some embodiments, media content server  104  validates (e.g., using key service) electronic devices  102  by exchanging one or more keys (e.g., tokens) with electronic device(s)  102 . 
     In some embodiments, media content server  104  and/or CDN  106  stores one or more playlists (e.g., information indicating a set of media content items). For example, a playlist is a set of media content items defined by a user and/or defined by an editor associated with a media-providing service. The description of the media content server  104  as a “server” is intended as a functional description of the devices, systems, processor cores, and/or other components that provide the functionality attributed to the media content server  104 . It will be understood that the media content server  104  may be a single server computer, or may be multiple server computers. Moreover, the media content server  104  may be coupled to CDN  106  and/or other servers and/or server systems, or other devices, such as other client devices, databases, content delivery networks (e.g., peer-to-peer networks), network caches, and the like. In some embodiments, the media content server  104  is implemented by multiple computing devices working together to perform the actions of a server system (e.g., cloud computing). 
       FIG.  2    is a block diagram illustrating an electronic device  102  (e.g., electronic device  102 - 1  and/or electronic device  102 - m,    FIG.  1   ), in accordance with some embodiments.

Furthermore, memory  212  and  306  optionally store additional modules and data structures not described above. 
     Although  FIG.  3    illustrates the media content server  104  in accordance with some embodiments,  FIG.  3    is intended more as a functional description of the various features that may be present in one or more media content servers than as a structural schematic of the embodiments described herein. In practice, and as recognized by those of ordinary skill in the art, items shown separately could be combined and some items could be separated. For example, some items shown separately in  FIG.  3    could be implemented on single servers and single items could be implemented by one or more servers. In some embodiments, media content database  332  and/or metadata database  334  are stored on devices (e.g., CDN  106 ) that are accessed by media content server  104 . The actual number of servers used to implement the media content server  104 , and how features are allocated among them, will vary from one implementation to another and, optionally, depends in part on the amount of data traffic that the server system handles during peak usage periods as well as during average usage periods. 
       FIGS.  4 A- 4 H  are example user interfaces for displaying a playlist on an electronic device  102 - 1 .  FIG.  4 A  illustrates representations of media items in a set of media items  406  that are included in Playlist A  402 . For example, the set of media items  406  includes media items  406 - 1  through  406 - 6  (e.g., and, optionally, additional media items not currently displayed on the user interface of electronic device  102 - 1 ). In some embodiments, each representation of a media item in the playlist includes an indication of the media item (e.g., cover art, a title, and/or additional information about the media item) and a set of options  407  (e.g., options  407 - 1  through  407 - 6  corresponding, respectively, to media item  406 - 1  through  406 - 6 ), for performing one or more actions related to the respective media item (e.g., as described below with reference to  FIG.  4 D ). In some embodiments, the user interface includes an option to play  404  the playlist (e.g., for playback at the electronic device, or for playback at another electronic device (e.g., electronic device  102 - m )). 
     In some embodiments, the set of media items  406  is stored in the playlist  402  as an ordered set of media items (e.g., where playback of the playlist includes playing back the set of media items  406  in the order at which they appear in the set). For example, for the user of electronic device  102 - 1 , the set of media items in Playlist A are stored (e.g., in a data structure) in association with the user account (e.g., stored using Playlist Module  224  at the electronic device and/or using Playlist Module  318  at the media content server  104 ). In some embodiments, the user is provided an option to shuffle the order of the media items in the playlist, which causes playback of the media items to be presented in an order different (e.g., randomized) from the stored order. 
     In some embodiments, the user interface includes an enhance option  408 . The enhance option  408  represents a setting to turn on recommendations to enhance Playlist A  402 . For example, the enhance option  408  is displayed concurrently with the display of representations of media items in Playlist A, as illustrated in  FIGS.  4 A- 4 H  (e.g., without requiring the user to navigate to another user interface to request recommendations). For example, instead of requiring the user to navigate to another user interface to view a list of recommended media items (e.g., recommendations selected based on a playback history of the user and/or recommendations of currently popular media items across all users of the media providing service), the user is enabled to select the enhance option  408  within the user interface that displays Playlist A, and in response to the user&#39;s selection (e.g., to toggle the enhance option “on”), the electronic device  102 - 1  automatically displays representations for recommended media items, as illustrated in  FIG.  4 B . 
     For example, while the enhance option  408  is toggled on, an indication  412  is displayed to show the user that Playlist A is currently “Enhanced” with recommended media items. In some embodiments, the recommended media items are selected in accordance with one or more properties of the media items in Playlist A. For example, recommended media items are selected as recommendations based on a similarity between the recommended media item and one or more of the set of media items  406 . For example, the recommended media items are selected in accordance with sharing a genre, artist, popularity, date, language, or other feature of one or more media items in Playlist A. 
     In some embodiments, the electronic device  102 - 1  interleaves recommended media items (e.g., at predefined intervals) within the set order of media items in Playlist A. For example, Recommendation 1 ( 414 - 1 ) is interleaved after 2 media items that are within Playlist A (e.g., media item A1 and media item A2), and before other media items in the playlist (e.g., media item A3 and media item A4). In some embodiments, a second recommended media item, Recommendation 2 ( 414 - 2 ) is interleaved at a same interval within the playlist as the first recommendation. For example, recommended media items are displayed after every 2 media items of the original Playlist A. In some embodiments, the interval at which to place recommendations within the playlist is determined based on user profile information (e.g., a playback history of the user to determine whether the user selects media items that the user has initiated versus media items that are recommended to the user by the media providing service). In some embodiments, the recommended media items are presented throughout Playlist A (e.g., without following a set interval). 
     In some embodiments, although recommendations are displayed as interleaved within the set of media items of Playlist A, the Playlist A is not modified (e.g., the set of media items stored in playlist module  224  and/or playlist module  318  does not change) to include the recommended media items. For example, the user is enabled to view the recommended media items while the Enhance feature is toggled on, but if the user returns to view Playlist A (e.g., in another listening session), the set of media items of Playlist A has not changed (e.g., the recommended media items are not added to the set of media items for Playlist A) (e.g., unless the user manually requests to add a recommended media item, as described below). In some embodiments, as described below, the user returns to the original view of the set of media items of Playlist A (e.g., shown in  FIG.  4 A ) in response to toggling the Enhance feature off. As such, the recommended media items are displayed for the user, and presented to the user during the current session while playing back Playlist A (e.g., with the Enhance feature toggled on), but are not stored as media items in Playlist A. 
     In some embodiments, the electronic device  102 - 1  displays an indication  416  that a number of recommended items has been added (e.g., 12 recommended items). In some embodiments, the number of recommended items is based on a number of media items in the original playlist. For example, in order to insert a recommended media item at an interval of every two media items, Playlist A includes at least 24 media items. 
     In some embodiments, the representations of the recommended media items are visually distinguished from the representations of the media items in Playlist A. For example,  FIG.  4 B  illustrates the recommendations displayed with italicized text. Other visually distinguishing features may be used; for example, the representations of the recommended media items may appear indented, with different shading and/or color, and/or with an indication (e.g., icon) next to the items, etc. 
     In some embodiments, the representations of the recommended media items are displayed with an option to add the recommended media item to the playlist. For example, the representation of Recommendation 1 is displayed with option to add  415 - 1 . In some embodiments, in response to the user selecting the option to add  415 - 1  a recommended media item to the playlist, the set of media items for Playlist A is updated to include the recommended media item, as described in more detail below. 
       FIG.  4 C  illustrates a user input  418  requesting to view additional options for Recommendation 1 ( 414 - 1 ). In some embodiments, in response to the user input  418 , the electronic device  102 - 1  displays a menu  420  including a plurality of selectable options for the media item (e.g., Recommendation 1), as illustrated in  FIG.  4 D . For example, the menu  420  includes options such as replace (e.g., to replace Recommendation 1 with another recommendation), add to library (e.g., to add the recommendation to the user&#39;s library of media content, as stored by the media providing service), and add to favorites (e.g., to add the recommendation to a list of the user&#39;s favorite media items, which the user can access using the media providing service). Alternative and/or additional options may be presented to the user in menu  420 . Further, in some embodiments, different menus are provided based on the media item associated with the menu (e.g., recommended media items include an option to replace, while media items from Playlist A includes a different set of menu options). For example, the menu options (e.g., for the media items in Playlist A that are not recommended media items) can include an option to remove and/or reorder media items in Playlist A. 
       FIG.  4 D  further illustrates receiving a user input  422  selecting “Replace” from the menu  420 . In response to the user input  422 , the electronic device  102 - 1  updates the user interface to replace Recommendation 1 with Recommendation 13 ( 414 - 13 ). For example, the electronic device replaces Recommendation 1 with a new recommendation at a same position in Playlist A. In some embodiments, the user selects (e.g., via user input  424 ), an option to add  415 - 13  the Recommendation 13 to Playlist A. In some embodiments, in response to the user adding the Recommendation 13 to Playlist A, Playlist A is updated (e.g., a data structure storing the set of media items in Playlist A is updated) to include Recommendation 13. In some embodiments, the media item that is Recommendation 13 is added to the end of the playlist (e.g., adding a recommended media item does not change the order of the original set of media items of Playlist A). In some embodiments, the media item that is Recommendation 13 is added to the playlist at the current position (e.g., interleaved between existing media items in Playlist A), which changes the order of the set of media items of Playlist A. In some embodiments, as illustrated in  FIG.  4 F , after the Recommendation 13 has been added to Playlist A, the option to add  415 - 13  is no longer displayed in the user interface for Recommendation 13 (e.g., and the representation of Recommendation 13 is optionally no longer visually distinguished from the media items of Playlist A). 
     In some embodiments, the electronic device  102 - 1  tracks the interaction of the user with the recommended media items and updates the recommended media items based on the user interaction. For example, if the user “skips” a recommendation (e.g., does not playback the recommended media item for more than a threshold amount of time (e.g., 30 seconds)), the electronic device  102 - 1  changes one or more other recommended media items that are displayed later in the set of media items (e.g., the next recommended media item (e.g., Recommendation 2) is updated to a different media item). In some embodiments, if the user requests to “replace” a recommended media item with another media item, the electronic device  102 - 1  updates one or more recommended media items that are displayed later in the set of media items (e.g., based at least in part on a similarity of the one or more recommended media items to the media item the user requested to “replace”). For example, the electronic device  102 - 1  changes the recommended media items based on the media items recommended to the user earlier in Playlist A that the user has listened to (e.g., or added to the Playlist A, or added as a favorite), and that the user has skipped or replaced, by updating the recommendation selection process to reflect the user&#39;s current preferences (e.g., as indicated by the user interactions). 
       FIG.  4 F  illustrates the user toggling the Enhance option off (e.g., by a user input  426  selecting the indication  412 ). For example, in response to the user input  426 , the representations of recommended media items are no longer displayed in the user interface displaying the media items of Playlist A. For example, in  FIG.  4 G , the set of media items  406  are redisplayed (e.g., as in  FIG.  4 A ) without any interleaved recommended media items. In some embodiments, recommended media items that were added to the Playlist A (e.g., while the Enhance option was on), are displayed in the user interface (e.g., because Playlist A has been updated to include the recommended media items). For example, Recommendation 13 would be displayed at the bottom of Playlist A (e.g., if the user scrolls down to view additional representations of media items in Playlist A). 
     The user is enabled to turn the Enhance option on and/or off by toggling the Enhance button  408 . For example, in  FIG.  4 G , the user selects the Enhance button  408  to toggle the enhance feature back on (e.g., after turning Enhance off in  FIG.  4 F ). In some embodiments, in response to the user toggling the Enhance option on, after the Enhance option has already been toggled on and off (e.g., at least once) during the current listening session, the electronic device  102 - 1  replaces the recommended media items with different recommended media items, as illustrated in  FIG.  4 H  (e.g., new Recommendation 14 ( 414 - 14 ) and new Recommendation 15 ( 414 - 15 ) are interleaved in Playlist A). In some embodiments, within a current listening session, the electronic device  102 - 1  does not replace the recommended media items with different recommended media content items (e.g., the same recommendations presented before the user toggled the Enhance option off are redisplayed for the user). 
     For example, the recommended media items are updated for distinct listening sessions (e.g., where the user has ceased playback for a predefined time period, or the user has exited an application of the media-providing service), such that during a subsequent listening session, new recommendations are presented to the user while the Enhance feature is enabled for Playlist A (e.g., even if the user never toggled the Enhance feature off before ending the previous listening session). In some embodiments, new recommendations are provided according to a predetermined time interval (e.g., every 24 hours). 
     Accordingly, the user is enabled to view recommendations within the user&#39;s own user-curated playlist (e.g., Playlist A) by toggling the “enhance” option on, and the user can easily remove recommended media items from being displayed (e.g., and played back) by toggling the “enhance” option off. This enables the user to experience recommended media items without modifying the user&#39;s original playlist, thereby providing an improved user experience. In some embodiments, the recommended media items are selected based on a similarity to the media items that are in the user-curated playlist. Thus, the user is provided with recommendations identified based on the user&#39;s user-curated playlist, and plays back the recommendations interleaved with the user&#39;s user-curated playlist, which provides a hybrid experience for the user to provide some variety (e.g., recommended media items) within the user&#39;s own user-curated playlist, without the user losing the user&#39;s original playlist (e.g., because the user-curated playlist is stored without being modified by the recommended media items). 
     It should be understood that, although  FIGS.  4 A- 4 H  describe a touch input on a virtual button to active/deactivate the enhance playlist features described herein, in some embodiments a speech input (or other user interface modality) may be used to trigger analysis operations. 
     Further, it should be understood that, although  FIGS.  4 A- 4 H  provide an example in which recommendations are interspersed within the user&#39;s own curated playlist, the user-curated playlist may have been partially curated by additional users (e.g., together with the user) and/or fully-curated by one or more other user&#39;s (e.g., the user is able to add recommendations to a friend&#39;s playlist). 
       FIGS.  5 A- 5 B  are flow diagrams illustrating a method  500  of providing media items to a user as recommendations within a user-curated playlist, in accordance with some embodiments. Method  500  may be performed at an electronic device (e.g., media content server  104  and/or electronic device(s)  102 ) having one or more processors and memory storing instructions for execution by the one or more processors. In some embodiments, the method  500  is performed by executing instructions stored in the memory (e.g., memory  212 ,  FIG.  2   , memory  306 ,  FIG.  3   ) of the electronic device. In some embodiments, the method  500  is performed by a combination of the server system (e.g., including media content server  104  and CDN  106 ) and a client device. 
     Referring now to  FIG.  5 A , in performing the method  500 , the electronic device provides ( 502 ), to a user (e.g., streams, plays back and/or displays on the electronic device, or on a second electronic device distinct from the electronic device), a user-curated playlist, the user-curated playlist including an ordered set of media items that were added by the user. For example, Playlist A described in  FIGS.  4 A- 4 H  is a user-curated playlist that includes a set of media items  406  selected by the user and added to Playlist A by the user. 
     In some embodiments, the user-curated playlist is a playlist curated by the user. In some embodiments, the user-curated playlist is a playlist curated by a user of a media providing service and made available to one or more other users (e.g., a public or shared playlist). In some embodiments, the user-curated playlist is a playlist that has been partially or fully curated by one or more other users (i.e., human users). In some embodiments, the user-curated playlist is a set of media items for which the user (or another user) has taken a predefined action in selecting or denoting media items (e.g., for which the user has indicated a media item as a favorite media item). That is, in some embodiments, the user-curated playlist is a playlist that is implicitly-curated (e.g., automatically) by the user through the user&#39;s action. In some embodiments, the user-curated playlist is a playlist that the user has expressly created and (e.g., manually) added media items to. 
     In some embodiments, the playlist need not be a user-curated playlist. Rather, in some embodiments, the playlist is a playlist that is curated for the user (e.g., algorithmically, based on a first recommendation algorithm). For example, in some embodiments, the playlist comprises a set of the user&#39;s (or another user&#39;s) most frequently consumed media items (e.g., the user&#39;s top tracks of the year). In some embodiments, the playlist is a “daily mix” generated for the user by the media providing service (e.g., using a recommendation algorithm for the daily mix). The user can then select an option to “enhance” the daily mix, as described below, by adding recommendations that are not generated by the first recommendation algorithm (e.g., that are generated by a second recommendation algorithm distinct from the first generated algorithm). For example, whereas the daily mix algorithm may tend to provide tracks that the user is familiar with, the enhance option may add “discovery” tracks that the user is less likely to be familiar with (e.g., using a discovery recommendation algorithm). 
     While providing a first media item in the ordered set of media items, the electronic device receives ( 504 ) a first user input selecting an option to include recommended media items in the user-curated playlist. For example, in  FIG.  4 A , the user input  410  turns on the enhance feature. In some embodiments, the first user input is a voice command (e.g., “Hey Spotify, enhance this playlist”). In some embodiments, the first user input is a single user input (e.g., a single tap on a virtual button, or a single voice command) that results in the inclusion of a plurality of recommended media items in the user-curated playlist (e.g., interspersed in the user-curated playlist). 
     In response to the first user input, the electronic device updates ( 506 ) the user-curated playlist to include a first recommended media item, the first recommended media item selected without user intervention based at least in part on attributes of the user-curated playlist. The first recommended media item is positioned in the user-curated playlist (e.g., displayed in a visual display of the playlist, or configured to be played back in the playlist) in between media items that were added to the ordered set of media items by the user. For example, in  FIG.  4 B , Recommendation 1 (e.g., the first recommended media item) is positioned in between Media Item A2 and Media Item A3 of Playlist A, such that the first recommended media item is interleaved with the media items added by the user. In some embodiments, the first recommended media item is not already included in the user-curated playlist (e.g., before the first user input, the user-curated playlist consists of items selected and/or added to the playlist by the user) (e.g., the first recommended media item is distinct from the media items in the user-curated playlist). For example, the first recommended media item is a media item presented to the user in addition to the media items of Playlist A. In some embodiments, the first recommended media item is selected without user intervention, but is only provided to the user in accordance with a user request to include the first recommended media item (e.g., in response to the user toggling the Enhance button on). In some embodiments, the electronic device provides an indication of the first recommended media item on a display of the electronic device (e.g., Recommendation 1,  FIG.  4 B ). 
     In some embodiments, the device provides one or more user-selectable options for (i) saving the first recommended media item to the user-curated playlist (to be available later) (e.g., option  415 - 1 ), (ii) requesting a different recommended media item to replace the first recommended media item, and/or (iii) playing (e.g., streaming) the first recommended media item without saving the first recommended media item to the user-curated playlist (e.g., the first recommended media item is not available in a subsequent session of the user playing back the user-curated playlist). For example, as described with reference to  FIG.  4 D , menu  420  includes a plurality of user-selectable options for Recommendation 1. In some embodiments, the first recommended media item is played (e.g., at its respective position within the playlist) automatically (e.g., Recommendation 1 begins playback after playback of Media Item A2 is complete), but the user is enabled to “skip” the recommended media item (e.g., before the recommended media item has begun playback, or during playback of the recommended media item). 
     In some embodiments, the first recommended media item is ( 508 ) an audio item. For example, the recommended media item comprises a song, a podcast, an audiobook, (or other spoken word). In some embodiments, the first recommended media item is a video content item. 
     In some embodiments, the electronic device displays ( 510 ) the user-curated playlist on a display of the electronic device, wherein updating the user-curated playlist to include the first recommended media item includes displaying an indication of the first recommended media item at its respective position in the user-curated playlist. For example, the playlist is presented as a list and indications of the recommended media items are displayed in the list at their respective positions, as described with reference to  FIG.  4 B . In some embodiments, the indications of the recommended media items are displayed with one or more visual properties distinct from the ordered set of media items that were added by the user (e.g., the recommended media items are displayed with an icon indicating they are not part of the original playlist). 
     In some embodiments, in accordance with a determination that the user selects the first recommended media item for playback, the electronic device updates ( 512 ) the user-curated playlist to include additional recommended media items for inclusion in the user-curated playlist. For example, the additional recommended media items are selected based at least in part on attributes of the first recommended media item. For example, if the user plays back Recommendation 1, the electronic device updates Recommendation 2 to a recommended media item that is similar to Recommendation 1. 
     In some embodiments, in accordance with a determination that the user does not select the first recommended media item for playback, the electronic device replaces ( 514 ) the first recommended media item with a second recommended media item at the position in the user-curated playlist in which the first recommended media item was positioned. In some embodiments, the user not selecting the first recommended media item comprises the user requesting to remove the first recommended media item (e.g., or to replace the first recommended media item, as described with reference to  FIG.  4 D ). 
     In some embodiments, the electronic device updates ( 516 ) the user-curated playlist to include a plurality of recommended media items and positions a respective recommended media item of the plurality of recommended media items according to a predefined interval in the user-curated playlist in between media items that were added to the ordered set of media items by the user (e.g., after every two media items from the user-curated playlist, a recommended media item is added as the third item, as shown in  FIG.  4 B ). In some embodiments, the predefined interval is a random interval (e.g., recommended media items are added at different positions in the playlist that are not defined according to a fixed interval). 
     In some embodiments, the electronic device receives ( 518 ) a second user input deselecting the option to include recommendations in the user-curated playlist. In some embodiments, in response to the second user input, the electronic device removes an indication of the first recommended media item from the user-curated playlist. For example, as described with reference to  FIGS.  4 F- 4 G , the user selects to toggle off the Enhance option (e.g., and the electronic device  102 - 1  removes the indications of any of the plurality of recommended media items from the user-curated playlist). 
     In some embodiments, the electronic device receives ( 520 ) a third user input requesting to save the first recommended media item to the user-curated playlist. In some embodiments, the electronic device, in response to the third user input, saves the first recommended media item to the ordered set of media items (e.g., when the user returns to their playlist (e.g., in a subsequent listening session), the recommended media item is saved as part of the playlist). In some embodiments, the recommended media item is saved within the playlist at the position in which it was presented. In some embodiments, in accordance with a determination that the user does not add the additional media item to the playlist, after the user returns to the playlist after a predefined time period (e.g., during a subsequent listening session), the playlist is presented without the additional media items (e.g., the original playlist is not modified with the recommended media items). 
     In some embodiments, the electronic device selects ( 522 ) a third recommended media item to include in the user-curated playlist based on user interaction with a previously presented recommended media item (e.g., the first recommended media item). For example, the electronic device determines if the user interaction is a positive or negative interaction, and if the interaction is a positive interaction, the device provides additional recommendations similar to the previously recommended media item that received the positive interaction. In some embodiments, if the interaction is a negative interaction, the device does not provide additional recommendations similar to the previously recommended media item that received the negative interaction (e.g., the device provides a recommendation for a dissimilar media item). For example, a negative interaction comprises “skipping” the recommended media item within a predetermined amount of time (e.g., during playback or before playback), a selection of a thumbs down/dislike button, and/or requesting the first recommended media item to be replaced by a different recommended media item. In some embodiments, a positive interaction comprises “liking” the recommended media item (e.g., selecting a heart indication or adding the media item as a favorite), playing back the full length of the recommended media item, and/or saving the recommended media item to the playlist. In some embodiments, a positive interaction comprises not receiving any user interaction (e.g., wherein the user does not remove the first recommended media item from the user-curated playlist). 
     Although  FIGS.  5 A- 5 B  illustrate a number of logical stages in a particular order, stages which are not order dependent may be reordered and other stages may be combined or broken out. Some reordering or other groupings not specifically mentioned will be apparent to those of ordinary skill in the art, so the ordering and groupings presented herein are not exhaustive. Moreover, it should be recognized that the stages could be implemented in hardware, firmware, software, or any combination thereof.
