This tip is only for the TouchPad

When playing music in the stock Music app, the default view of seeing your music is as a simple listing of all the available tracks. However, you are able to switch to a fullscreen Album Art view of your music by tapping on the  icon in the bottom right of the screen. This will also show you a sneak peak of the prior and next song as well, where you can swipe right or left, respectively, to move to preview that track and then tap on the album art to start playing it. If you want to exit the full screen view, just tap the new  icon on the bottom right of the screen.
