If you want to explore new music, and you already spend a lot of time in front of the computer, you should check out the streaming audio on Lala. It's free, and every computer geek knows how to capture the cached audio data for repeat plays. The streams are of decent quality (they say at 128kbps, but many sound better and a few worse. I'm not an audiophile, I don't want to fetish on the purity of sound at the expense of the music.) and the libary is so vast you'd think this offering criminal. I like the service so much I've set up a separate PC to run the streams. Do yourself a favor and check it out.
