Spotify's jukebox takes song requests from your t-shirt

Perhaps I'm a little late to the party with this one, but did you know that Spotify has installed a jukebox at SXSW? It's no ordinary jukebox, though. Users don't have to insert coins to choose their desired tracks; instead, they simply stand in front of the True Fan Jukebox in their favorite band tee and the machine does the rest.
