While I'm not a Harvard student, I'm vaguely affiliated through some friends of mine with Harvard Free Culture, a local Free Culture chapter. They are, after all, just up the street. One of our newest projects is the Free Music Project. The goal, is, well, to gather together music under free licenses, both for just making a centralized collection of free music and for other specialized purposes, like providing music to go on OLPC laptops and school servers.
So, go find free music, or if you're an artist, re-release your music under a free license or record some new stuff. (If you're in the Boston area, Antenna Alliance can help you get your music recorded for free. Who knows, maybe your music will end up on millions of laptops.
