If you haven't discovered the usefulness of this personalized online radio station, hurry up. With the costs of licensing music on the Web going up, up, up, Pandora is reportedly very close to shutting down. The music industry apparently doesn't need any new customers. The site was created for curious fans who don't know that Dusty Springfield came before Amy Winehouse or which newer bands take after Nirvana. All you do is type in a band name (or a song), and the site assembles a playlist of similar groups. You could spend all day listening to songs that sound like Joy Division or U2 (although, all you really need to do is put on an Interpol or Coldplay tune).
