It would be very nice if songs in the music library also list the playlists they have been added to (trimmed to "Playlist 1 - Playlis..." and in a different font color or something).
Usage Scenarios:
- I'm making a quick playlist of all my favorite songs, which is something I don't really have time to do in one sitting. On the second, pass, I can't remember which songs I've already added, which means I need to open the list in one tab and compare songs, or just continually add every favorite I see - a tedious task when my favorites number nearly 1,000 already of of a ~10k collection from almost 1,000 CD's.
- I want to know which songs in an album are on my "Party" playlist. Right now I have to hope the songs are in order by Artist+Album on the Playlist tab, or I need to search manually through the playlist for each song.
- Playlist 1 and Playlist 2 are supposed to be two different sets of music, but they have a couple overlapping songs by certain artists. Right now I have to compare each by hand.
