Music Control lets you control music play back with either big buttons that cover the entire screen or swipe controls in either horizontal or vertical orientation with the album art work in the background. You can also access your music library from within the application to control the content.
Makes controlling music a lot easier while in the car or while sitting at a desk with an ipod/iphone playing music.
If you plug in your iphone/ipod it will stay unlocked while playing music.
