Abstract

A method and computer program product for defining an active playlist of media tracks for rendering in a defined sequence. A portion of the media tracks defined in the active playlist are rendered. A shuffle command is received from a user concerning the active playlist. A non-rendered playlist is generated. The non-rendered playlist defines one or more non-rendered media tracks included within the active playlist and excludes one or more rendered media track included within the active playlist. A rendering sequence is defined for the non-rendered playlist.

Claims

1. A method comprising:

defining an active playlist of media tracks for rendering in a defined sequence;

rendering a portion of the media tracks defined in the active playlist;

receiving a shuffle command from a user concerning the active playlist;

generating a non-rendered playlist, wherein the non-rendered playlist defines one or more non-rendered media tracks included within the active playlist and excludes one or more rendered media tracks included within the active playlist; and

defining a rendering sequence for the non-rendered playlist.

2. The method of claim 1 wherein generating a non-rendered playlist includes:

identifying one or more rendered tracks included within the active playlist;

and

identifying one or more non-rendered tracks included within the active playlist.

3. The method of claim 2 wherein generating a non-rendered playlist includes:

comparing the one or more rendered tracks included within the active playlist to the one or more non-rendered tracks included within the active playlist to identify one or more common tracks; and

removing the one or more common tracks from the one or more non- rendered tracks included within the active playlist, thus defining the non-rendered playlist.

4. The method of claim 2 wherein defining a rendering sequence for the non-rendered playlist includes:

selecting a first track for rendering from the non-rendered playlist;

rendering the first track;

removing the first track from the non-rendered playlist, thus defining a modified non-rendered playlist; and

selecting a second track for rendering from the modified non-rendered playlist.

5. The method of claim 2 wherein defining a rendering sequence for the non-rendered playlist includes:

defining a non-rendered track rendering sequence for two or more of the non-rendered tracks defined within the non-rendered playlist; and

rendering the two or more non-rendered tracks in accordance with the non-rendered track rendering sequence.

6. The method of claim 2 further comprising:

defining one or more supplemental tracks for adding to the non-rendered playlist.

7. The method of claim 6 further comprising:

comparing the one or more supplemental tracks to the one or more non-rendered tracks defined within the non-rendered playlist to identify one or more common tracks;

removing the one or more common tracks from the one or more supplemental tracks, thus defining one or more non-common supplemental tracks.

8. The method of claim 7 further comprising:

adding the one or more non-common supplemental tracks to the non-rendered playlist.

9. The method of claim 7 wherein the method is executed, at least in part, on a server computer.

10. The method of claim 1 wherein the method is executed, at least in part, on a client electronic device.

11. A computer program product residing on a computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:

defining an active playlist of media tracks for rendering in a defined sequence;

rendering a portion of the media tracks defined in the active playlist;

receiving a shuffle command from a user concerning the active playlist;

generating a non-rendered playlist, wherein the non-rendered playlist defines one or more non-rendered media tracks included within the active playlist and excludes one or more rendered media tracks included within the active playlist; and

defining a rendering sequence for the non-rendered playlist.

12. The computer program product of claim 11 wherein the instructions for generating a non-rendered playlist include instructions for:

identifying one or more rendered tracks included within the active playlist;

and

identifying one or more non-rendered tracks included within the active playlist.

13. The computer program product of claim 12 wherein the instructions for generating a non-rendered playlist include instructions for:

comparing the one or more rendered tracks included within the active playlist to the one or more non-rendered tracks included within the active playlist to identify one or more common tracks; and

removing the one or more common tracks from the one or more non-rendered tracks included within the active playlist, thus defining the non-rendered playlist.

14. The computer program product of claim 12 wherein the instructions for defining a rendering sequence for the non-rendered playlist include instructions for:

selecting a first track for rendering from the non-rendered playlist;

rendering the first track;

removing the first track from the non-rendered playlist, thus defining a modified non-rendered playlist; and

selecting a second track for rendering from the modified non-rendered playlist.

15. The computer program product of claim 12 wherein the instructions for defining a rendering sequence for the non-rendered playlist include instructions for:

defining a non-rendered track rendering sequence for two or more of the non-rendered tracks defined within the non-rendered playlist; and

rendering the two or more non-rendered tracks in accordance with the non-rendered track rendering sequence.

16. The computer program product of claim 12 further comprising instructions for:

defining one or more supplemental tracks for adding to the non-rendered playlist.

17. The computer program product of claim 16 further comprising instructions for:

comparing the one or more supplemental tracks to the one or more non-rendered tracks defined within the non-rendered playlist to identify one or more common tracks;

removing the one or more common tracks from the one or more supplemental tracks, thus defining one or more non-common supplemental tracks.

18. The computer program product of claim 17 further comprising instructions for:

adding the one or more non-common supplemental tracks to the non-rendered playlist.

19. The computer program product of claim 17 wherein the computer program product is executed, at least in part, on a server computer.

20. The computer program product of claim 11 wherein the computer program product is executed, at least in part, on a client electronic device.
