Its a decent app. It has lot of stations though not all of them stream music.
Problems -
1. You cannot listen to music while doing other stuff. Once I play music and press the home button to open something else, it stops playing music. I did upgrade to ios 4.2 which has multitasking features. But it seems app is not designed for a multitasking environment.
2. Other problem which is minor is that when I change my iPad from portrait to landscape, the app does not follow through and does not change its orientation. Sometimes, it does, but it takes like more than 10 seconds to do it.
If you just want to stream music, its good.
