Right, who doesn't use WinAmp? After all, it does whip the laama's ass. Anyway, on to the point: Shoutcast offers endless audio streams of endless genres of music for you're listening pleasure. If you're like me, and limited to two or three (barely) tolerable local radio stations, this alternative can be a Godsend - and hey - it's commercial free!
