Wouldn't it be great if the Library, which includes all songs from all of ones playlists and starred, would also show in which playlist a song currently is? For example: I go to the Library and search "Justin Timberlake". Now I'm seeing all of the Justin Timberlake songs I have in my library. I'm seeing the song Titles, Times, Albums, etc. But no where does it show in which of my playlists a song currently is! It should do that!
Summary: Currently, there are 6 columns in the Library: Title, Artist, Time, Album, Date it was added, and User. A seventh column named "Playlist" should be added that shows us in which Playlist one has added a song.
In addition, I think it would be wonderful if one could exclude/include playlists in the Library.
Example: Say I want to listen to all my songs from some of my playlists. Right. So I go to the Library and shuffle. But I've got a playlist of Fulham FC chants and a playlist of rather awkward soothing ocean sounds. So to avoid listening to those playlists and only listen to decent music, I want to exclude them from the library.
Summary: Say a seventh column "Playlists" is added to the Library. If I click it all the songs are ordered by Playlists. Now I should be able to "tick off / tick on" a group of songs from a playlist which, e.g.. Is ticked off, won't be included if I decide to shuffle play the songs in the Library.
