How does the music widget work when I'm using Quick Cover?
It is possible to contiune playing music while in the Quick cover mode. Quick Cover can control your Music via the Music Widget. Like
the existing Music Widget found in full screen mode, the Play/Pause/Next/Previous Controls will be available to you.
While your music is being played in the background and with Quick Cover closed, left flicking the Quick Cover Widget displays the
Music Widget, you can then use button click to Control the music.
