Music Player  App use of more power...!!! It has pause and change of song but not stability once only it visible and if screen off and after on invisible. Lockscreen and active mode should both in same option and in notification tray it should be invisible. I don't like it Using More Ram and Battery fix it and not stabile some times. Gestures should have access to use phone apps.it can be easily bypassed by pressing minimize button home button  accidentally touch or pressing of any button fix it  R u work r not no update for your app I hate u...!!
