I'm really pleasantly surprised by this. My roommate showed me a site for AOL XM, he's as picky about this stuff as I am. Surprisingly they play very good stuff. Right now I'm listening to the Jungle/Drum&Bass channel and they're playing a HUGE oldskool track, Doc Scott - Unofficial Ghost, and before that it was Xample and Sol - Ruthless. They're doing a great job it seems of covering the best and most legit stuff from every genre.
Anyway to anyone interested take a listen:
