ANd I second woxy.
All 3 stream on the net. Triple J is from Sydney, Australia, Indie 103 is a brand new Clear Channel (!) owned station in LA - don't know how long it's gonna last or not suck, and woxy is from somewhere in Ohio, I think.
I hear tons more good music on any those outlets than anywhere else, especially anywhere commercial...
Oh, and MTV2 from 2000 - 2001, if you have a time machine.
