Along the vein of radio paradise (which is pretty much great), there are two shoutcast stations I listen to pretty regularly:
http://nugs.net and
http://stumbleinthedark.com. Both are quite cool if you're into jam bands, and stumble has been known to slip in such greatness as Pedro the Lion every once in a while. Nugs is the favorite, though, as it tends to play entire live shows by different jam bands, and often offers the entire show for 128kbps mp3 download.

edit: Also, people in Pittsburgh, Listen To More Public Radio. 91.3fm WYEP is insanely great, and they do a lot of cool stuff in the community. Not too long ago I got the chance to go down to a little theatre in, I believe, 'Sliberty (East Liberty to non-residents) and see The Beatles' "Hard Day's Night" film. Just cool, especially for a young kid who didn't get to see all this stuff when it was the big thing.
