Pictureshow Films and the AV Club at The Onion made a list of 25 songs and invited 25 bands to come into their office and cover them, first come, first sing. The first band gets to choose from all 25 songs, the next from 24 etc, etc, until there is one song and one band left. The songs are all listed, but the bands are secret until their song gets posted.
So far Ted Leo and The Pharmacists covered Tears for Fears and Fruit Bats covered Hall and Oats. Next up, Starship's "We Built this City" and I can't wait to see who wanted to sing that!
