When you do this too fast after first selecting a song the screen will get stuck with your library on the very top of the screen and the screen you were just on covering the majority. My “one small problem” is that when I select a song and it opens I usually swipe back down so I can add more songs to my queue, or just avoid watching an add when I don’t want to watch a music video.
I love this app and don’t consider using another music app.
