Been listening to this internet radio for a couple years now. It's the only one I listen to and its free. Sound quality is good (128K).
Main Channel is for the Industrial crowd
80's channel is a pretty cool channel. None of the cheese but all the good. And they play a tonne of rare remixes you havent' heard before. Here's a list of the last 10 Bands played on the 80's channel:
Flesh for Lulu
Love and Rockets
Echo and the Bunnymen
Fun Boy Three
