From the very first day of the iPhone App store, we’ve loved Pandora Radio. This App is basically the same thing you get at the Pandora Web site, but on your iPhone. You can listen to streaming music based on a song or artist you choose. As you indicate how much you like each song that is played, Pandora continues to customize the music. The App is free, as Pandora is advertising supported. This App makes your car’s FM radio obsolete.
