I love online music! Personally I use SHOUTcast, a free service provided by the makers of WinAmp. They currently list over 8,000 stations. I listen to it all day at work, and also have it set up here at home so I can play the music out through our stereo system. The range of genres is fantastic, and you get to hear from quality artists that don't have the corporate backing to get radio play. I've discovered a number of great bands that I never would have heard of on regular radio.
