Apple updated the big things as well as the little things in iOS 7. One of the smaller features is a fresh now look that'll grace the Music app. Cover flow is phased out and replaced with a new album art-driven UI. You'll be able to tap on an artist and view all their songs from your library, whether they are saved to your device or stored in the cloud. The Music app also features a new iTunes Radio feature that's similar to Pandora.
