The listener-funded radio station that runs the archive, WFMU, is the single greatest radio station in the world.
Thanks for the tip! In return, for people who are into this sort of thing but don't know about these (listener-supported radio stations/streams and free music archives):
-Radio Paradise [1]
-SomaFM [2]
-Jamendo [3]
-Magnatune (not quite free but close enough) [4]
-And all the Icecast streams [5]
