Pros: awesome control of sound and is great with the headphones. Good syncing to iTunes and it looks decent and is easy to use.
Cons: Freezes way too much to run a constant stream of music. Doesnt work unless open, thus killing battery life. Also, the inability to create playlists is rather annoying.
Overall: While the function and purpose of the app is nice, it lacks in ease of casual use. My opinion would be that it would be better as an iPod music player add-on than as a separate app. This would allow more flexibility and improve overall function. Generally, a Decent app, best used with low-grade stereos or headphones. Not the greatest when doing anything but sitting around (preferably with a charger nearby).
