It's almost impossible to make playlists longer than a couple songs. New playlists should be able to be created from the edit screen and you should be able to just tap the songs you want in the playlist while in the edit screen. It's too frustrating the way it is now. Also, it keeps glitching when you try to add more than a few songs into a playlist. And for the love of all things good, make those ads at the beginning shorter if they can't be removed at all. They're so annoying to wait with the headache-inducing noises they make.
Thank.
