I just happened across the homepage of DoKashiteru, a duo whose music I have used liberally in recent video projects - Gameshelf included. They put much of their work into the Creative Commons under remix-friendly licenses, so I plan on continuing to use it as an aural background for my own stuff. (Before today I knew the band's music via its page on ccMixter, the site I raid for all my legally clean background music needs.)
They really hit the spot for the kind of blip-happy electronica I'm quite fond of, and I encourage you give them a listen. They make videos, too: here is Sander, one of the pair, giving you a lesson on how to torture some chunky sounds out of an ancient, analog Moog synthesizer.
