last.fm
Web 2.0 musicmeister Last.FM and CBS's "unprecedented new service" is a leveled-up Last.fm: It is "the most complete, licensed music catalog" in the world with music from all four major labels and 150,000 indie labels, or what they're calling "the world's best jukebox." It's all available on demand (right now!) without logging in, is free (banner ad-supported) and now plays full tracks from artists you can search for directly—internet radio on 'roids, basically. But of course, there are limitations thanks to label tightassness, the biggest point of suck being that you can only listen to a song three times.
