I can't find a way to make the player close once I've launched it. That is, there's always an item on the notification bar and a player widget in the notification list (or whatever it's called when you swipe down from the top of the screen).
It's convenient to have it persist somewhat, but all the other players I use (like Tidal, Google Play, etc.) have some way to explicitly close it once I'm done. Is there a way to close it without restarting the phone?
