Notes:
- These playlists allow access to the subsonic feature of pulling new, frequently played, and so on albums.
- See: http://www.subsonic.org/pages/api.jsp#getAlbumList for the subsonic description
- The subsonic api is inherently album oriented. Therefore at the moment the "count" argument for GenerateMore is used as the number of albums to pull, which hopefully isn't a problem.
- Could be made more efficient by multi-threading the fetch of the songs for each album
