Claim 5:
6. A media player system, comprising:
at least one user interface including an input user interface and an output user interface;
a memory storing a program; and
a processor coupled to the at least one user interface and the memory, the processor being controllable by the program to perform a method including:
receiving, by way of the input user interface, a selection of a play button;
playing simultaneously, by way of the output user interface and in response to the selection, two different versions of a same musical song including a first version and a second version of the same musical song, the first version including an instrumental component and a vocal component, and the second version including either: (i) the instrumental component of the first version and not the vocal component of the first version or (ii) the vocal component of the first version and not the instrumental component of the first version;
while the two different versions are being played simultaneously by way of the output user interface of the media player, receiving a volume adjustment by way of an adjustment of a volume control of the input user interface of the media player, the volume control being configured such that an adjustment of the volume control in a first direction increases a volume of a first of the two different versions being played by way of the output user interface of the media player and decreases a volume of a second of the two versions being played by way of the output user interface of the media player, and such that an adjustment of the volume control in a second direction different from the first direction decreases the volume of the first of the two different versions being played by way of the output user interface of the media player and increases the volume of the second of the two versions being played by way of the output user interface of the media player; and
in response to receiving the volume adjustment, increasing a volume of one of the versions being played by way of the output user interface of the media player and decreasing a volume of the other of the versions being played by way of the output user interface of the media player.
