The floating lyrics won't stay open. It shows lyrics for a few seconds and then it closes randomly and won't open until the next song comes up. And then it repeats the same problem. As for the music that I listen to, there are so many songs with extremely incorrect lyrics to the point where using the app is pointless since you don't allow any of them to be changed. And the songs that don't have any lyrics, I can't add them because that option isn't there.
