We haven't listened to the radio in years. Often there are more commercials than songs, and blocks of commercials can last forever. Then you get to hear the same twenty hit songs over and over. If you live in a city with great radio, you're lucky, as media consolidation homogenizes everywhere else.
People complained that the iPhone didn't have an AM/FM tuner in it, but what if your radio wasn't just limited to your immediate area? What if you could spin that dial and tune in to stations all over the globe? If you're a radio aficionado, that's an app worth having.
