Music Controls on Lock Screen.
Every once in a while I turn on my phone and I see the new iOS 11 Music Control sort of Notification. I don't have the app open, no sound is playing, it is just there. I do know that if I restart my phone it will no longer be there. If i don't restart my phone then it will disappear about a day later. I would just like to know what was causing it.
iPhone 6, iOS 11.0.2, Actually running iOS 11 Beta 1
