Abstract

Various systems and methods described above permit a user'"'"'s content experience (e.g. music playing experience) to be monitored and for metadata describing this experience to be collected. This metadata can be dynamically updated as a user experiences media content and then used to impart to the user a personalized experience that is tailored to that specific user. A user'"'"'s metadata can, in some instances, provided across a wide variety of computing devices on which the user may experience the media content, thus standardizing the user'"'"'s personalized media experience. In addition, intelligent or “smart” playlists can be provided which, in some instances, can be dynamically and automatically updated to reflect current user experiences, thus providing a highly personalized and enjoyable content experience.

Claims

1. A system comprising:

a computer readable storage medium; and

a playlist of media content stored on the computer readable storage medium, the playlist having a file format comprising;

a first portion containing data associated with one or more users of the playlist; and

a second portion containing data associated with the playlist, the second portion comprising;

a first path to the media content in a first file system;

a static portion that contains one or more lists of media content for the one or more users of the playlist;

one or more individual identifiers associated with individual media content and configured to update an existing path to the media content that is a subject of the playlist; and

wherein the one or more individual identifiers comprise at least one universal content identifier associated with a particular piece of media content or a file system tracking identifier associated with a particular piece of media content;

wherein the computer readable storage medium having instructions that, when executed by a processor;

to use the individual identifiers to update the first path to the media content in the playlist to create a second path to the same media content in the playlist using the universal content identifier if the media content is stored in a different location in the first file system or in a second file system.

2. The system of claim 1, wherein the universal content identifier of the media content remains constant when metadata associated with the media content changes.

3. The system of claim 1, wherein said one or more identifiers are globally unique identifiers (GUIDs).

4. The system of claim 1, wherein the second portion comprises a dynamic portion that defines one or more queries for dynamically updating the playlist, the queries are executed to produce a result set that is provided into the static portion to define the list of media content.

5. The system of claim 4, wherein the dynamic portion contains references to one or more filters used to query one or more databases.

6. The system of claim 4, wherein the dynamic portion contains references to one or more content-adding filters used to query one or more databases.

7. The system of claim 4, wherein the dynamic portion contains references to one or more content-removing filters used to query one or more databases.

8. The system of claim 1, wherein the first portion contains data associated with multiple users.

9. The system of claim 1, wherein the first portion contains data associated with multiple users, the data comprising one or more user ratings that can rate the playlist.

10. The system of claim 1, wherein the static portion contains data associated with when the static portion was created.

11. The system of claim 1, wherein the static portion contains data associated with when the static portion expires.

12. The system of claim 1, wherein the static portion contains data associated with the user that created the static portion.

13. The system of claim 1, wherein the static portion contains data associated with at least one path to the media content that is a subject of the playlist.

14. A computer-readable medium having one or more instructions executed by one or more processors, the one or more instructions causing the one or more processors to:

provide a playlist of media content defined by a file format comprising;

a first XML portion containing data associated with one or more users of the playlist; and

a second XML portion containing data associated with the playlist, the second XML portion comprising;

a first XML path to the media content in a first file system;

a static XML portion that contains one or more lists of media content for the one or more users of the playlist;

one or more individual identifiers associated with individual media content and configured to update an existing path to the media content that is a subject of the playlist;

wherein the one or more individual identifiers comprise at least one universal content identifier associated with a particular piece of media content or a file system tracking identifier associated with a particular piece of media content; and

use the individual identifiers to update the first path to the media content in the playlist to create a second path to the same media content in the playlist using the universal content identifier if the media content is stored in a different location in the first file system or in a second file system.

15. The computer-readable medium of claim 14, wherein the universal content identifier of the media content remains constant when metadata associated with the media content changes.

16. The computer-readable medium of claim 14, wherein said one or more identifiers are globally unique identifiers (GUIDs).

17. The computer-readable medium of claim 14, wherein the second XML portion comprises a dynamic XML portion that defines one or more queries for dynamically updating the playlist, the queries are executed to produce a result set that is provided into the static portion to define the list of media content.

18. The computer-readable medium of claim 17, wherein the dynamic XML portion contains references to one or more filters used to query one or more databases.

19. The computer-readable medium of claim 17, wherein the dynamic XML portion contains references to one or more content-adding filters used to query one or more databases.

20. The computer-readable medium of claim 17, wherein the dynamic XML portion contains references to one or more content-removing filters used to query one or more databases.

21. The computer-readable medium of claim 14, wherein the first XML portion contains data associated with multiple users.

22. The computer-readable medium of claim 14, wherein the first XML portion contains data associated with multiple users, the data comprising one or more user ratings that can rate the playlist.

23. The computer-readable medium of claim 14, wherein the static XML portion contains data associated with when the static XML portion was created.

24. The computer-readable medium of claim 14, wherein the static XML portion contains data associated with when the static XML portion expires.

25. The computer-readable medium of claim 14, wherein the static XML portion contains data associated with the user that created the static XML portion.

26. The computer-readable medium of claim 14, wherein the static XML portion contains data associated with at least one path to the media content that is a subject of the playlist.
