I need to do something slightly different for each Playlist.
* Collection: I load tracks from the collection_view, which filters
tracks to those where the library is enabled but not deleting.
* Favorite Tracks: I load tracks from the favorites_view, which filters
tracks based on the tracks.favorite and library.deleting column.
* Most Played Tracks: I load tracks with a playcount greater than the
average playcount of all tracks (rounded up to the nearest integer).
* New Tracks: I load tracks that have been added within the last week.
* Previous Tracks: I load tracks that have been played since startup
using the system_tracks table. I take care to clear these entries
in the table during startup.
* Queued Tracks: Load tracks from the user_tracks table.
* Unplayed Tracks: I load tracks with a playcount equal to 0 and remove
when they are played.
* User-Defined Playlists: Load tracks from the track_playlist_link
table.
Additionally, I implement move_track_up() and move_track_down() support
for user playlists and queued tracks.
Finally, I update the have-next-track property to take into account if
the Collection has tracks too.
