Configuring a playlist or sequence of compositions or stream of compositions

Apparatus to help user(s) to configure a playlist and/or a sequence of compositions, comprising:

• electronic-display(s) that:
• display a first ordering of compositions that represent compositions available to be added to said playlist and/or sequence of compositions;
• and an indicator that designates one of said compositions as the current-location in said first ordering;
• display a second ordering of compositions that represent a playback order of said playlist and/or sequence of compositions;
• and a second indicator that designates a current-location in said second ordering;
• electronic-circuitry and/or processor(s) that:
• associate at least one recognition sound-segment with each composition in said first and/or second ordering of compositions;
• wherein a beginning portion of said recognition sound-segments is more quickly recognizable to the user than a beginning playback of its associated composition;
• in response to user-action(s) to navigate to a new current-location in said first ordering:
• play the recognition sound-segment that is associated with the composition at the new current-location in said first ordering;
• and
• when command-action(s) by said user(s) is detected:
• add the composition that is associated with the sound-segment at the current-location in said first ordering, into said second ordering at the current location designated by said second indicator.

One or more computer-readable memories or storage media, not including carrier-waves, having computer-readable instructions thereon which, when executed by electronic-circuitry and/or processor(s), implement a method to help user(s) to configure a playlist and/or a sequence of compositions, said method comprising:

• displaying, on electronic-display(s), a first ordering of compositions that represent compositions available to be added to said playlist and/or sequence of compositions;
• and an indicator that designates one of said compositions as the current-location in said first ordering;
• displaying, on electronic-display(s), a second ordering of compositions that represent a playback order of said playlist and/or sequence of compositions;
• and a second indicator that designates a current-location in said second ordering;
• associating, by electronic-circuitry and/or processor(s), at least one recognition sound-segment with each composition in said first and/or second ordering of compositions;
• wherein a beginning portion of said recognition sound-segments is more quickly recognizable to the user than a beginning playback of its associated composition;
• in response to user-action(s) to navigate to a new current-location in said first ordering:
• playing, by electronic-circuitry and/or processor(s), the recognition sound-segment that is associated with the composition at the new current-location in said first ordering;
• and
• when command-action(s) by said user(s) is detected:
• add the composition that is associated with the sound-segment at the current-location in said first ordering, into said second ordering at the current location designated by said second indicator.
