Its GREAT!! But a tiny problem

I love this app because it lets me sign into YouTube and I can listen to music without wifi or using my internet! I really have a problem besides the fact that sometime when I am listening to music and turn it off, it dont show what song is playing and Ive deleted it a couple time ad then it works again but them sometimes it dont so I have to re-do everything. The other thing is that it use to glitch like I would try to click the playlist button part but then it would blank out and I could not play any certain playlist. Other than that I think that it is a GREAT app and the bet one I have had so I hope it doesnt glitch or mess up anymore
