The Playback screen opens and the song you tapped or the first song in the album or other playlist starts to play.

If you choose a repeat option (using the Repeat icon ), playback only stops when you stop it.
Tap here to restart, pause, play, or skip.
You can return to the Playback screen from most other screens in the Music application by tapping the currently playing song at the bottom of the screen (when held upright), or tapping the Music icon at the top right corner of the screen (when held sideways).
You can return to the Playback screen from any other application by opening the Notifications panel and tapping the ongoing music notification.
