Just a quick unsolicited plug. Looking for something fun to listen to while you surf, hack, or do whatever on your computer? Check out the Secret Agent station at SomaFM.com. I don't know where they find this music, but it's incredibly cool. If my life had a soundtrack, I'd want it to sound something like this.

If you have iTunes, it's right there in your "Radio" section, under "Electronica". There are other ways to listen at the SomaFM site.
