I realize I started out doing this wrong, but it would be nice if there were a way to fix it. I started by liking songs without organizing them in a playlist. Since then I have moved the ones I want to save (premium) on my device to playlists.
1. It would be nice to be able to say "remove songs that are not in any playlist"
2. As an alternative, have a filterable column that says how many playlists the song is in.
This falls under the general category of set operations on playlists, but for songs instead. It is too bad you keep pushing off the set operations. It is easy to implement, and you can hide it away where only us mathematical sorts will look for it.
