It keeps going when you leave
Playback does not stop because you did something else.
- Audio keeps playing with the screen off and while you use another app
- Video moves into Picture in Picture when you leave the app, and comes back to the card when you return
- Lock Screen and Control Center get artwork, play/pause, next and previous, and skip back or forward 15 seconds
- AirPlay through the system route picker, and a car mode built for a phone on a dashboard
