Anyone have this glitch/issue?

I wasn't really focused and I started a multi-live. I noticed when a song got picked that there was no sound despite my phone volume being on. During the live, the notes were a bit laggy/slower/jerkier than usual. The fever was messed up, but it seemed to have gone through. The song finished, but now there's the screen with the stage and chibis with nothing happening. Everything's swaying, but the game isn't going to the final live screen...

??? Help?
