Probably the most popular free radio application on the App Store, Pandora allows you to create personalized radio stations based on your favorite musical group or genre. Creating a custom radio for your favorite musical group is easy to do, but I noticed that Pandora does play songs by other groups as well but bases its choices on your music groups’ style. The controls allow you to skip to the next song, pause music, or give the song a virtual thumbs-up or thumbs-down, which helps build your music preference profile over time. A convenient pop-up menu allows you to bookmark the song or artist currently playing, buy the song in iTunes, or share your favorite station with a friend via e-mail. Many songs contain bios of the actual group playing. Audio quality was very good over 3G with only 2 pauses to buffer music playback. Pandora does have an option to improve 3G audio quality, although its disclaimer states that skips and hesitations will increase if activated. I did not test this feature since performance was good overall with acceptable load times. However, the radio did not always resume after a phone call.
