So there are two issues:
1) You can't sort a playlist by Arist or Song
2) You can't delete a song when you are on the "cover art" screen
This creates an issue when I want to modify playlists live. There is no "remove from playlist option" when I listen to the song, nor is there a sort option so that I would at least be able to sort and find the song that way. Now I have to look through a thousand song playlist to remove a song that I accidently added.
