Rock'on
Rock'on was my first Android app. It was a music player that offered a swifter music library visualization based on album art. "Was" because it has been discontinued and is no longer available on the Market.
Download
Although Rock'on has been removed from the Market you still download it from here. Rock'on is also open source and you can find it at:
