Noticed since iOS 11 at random times the music player would be in Notification Center. I have to quit the Music app (which wasn’t running in the background prior by the way) to get it to go away, until it unfortunately pops back up again.

Yes this is happening to me no idea how to stop,it
Also noticed my info screen on my BMW when connected to Bluetooth won’t show the song information and wondering if all this is connected somehow.
