So one of the "big" apps released today was iHeartRadio, which basically allows you to stream via internet radio stations from around the U.S. Perfect for you folks who travel and need your talk radio fix, or like to have some background radio while you work.
The app is free, though there is a premium area for some high-profile talk radio. Overall it feels pretty solid. The graphics have some banding, which could be easily fixed with a different background and the selection is decent, but not as great as internet radio. Well worth the download though if radio is your thing.
