Since it’s release with the launch of the App Store, the Pandora Radio App has been one of our favorites and is consistently one of the top downloaded apps from the App Store.  As with the web application, Pandora lets you create stations by artist, song, or genre.  Featuring biographical information for the currently playing artist, a track progress bar, and the visually stunning Cover Flow mode, it’s likely to be one of your favorite apps if you don’t already own it.
