One of my least favorite parts about organizing my songs is the fact that the "recently played" feature is only in the Group tab and not the Sort tab. I would personally love to use this because if I wanted to play a song but forgot what it was called, I could just go back in order and find it much easier. I don't see what the point of recently played is if you are just going to separate it by difficulty or whatever. Going back in chronological order would just make much more sense.
