Here's coolness: The Creative Commons--in cooperation with Negativland, Wired magazine, and a group of 16 bands (including My Morning Jacket, Beastie Boys, and Chuck D)--has put together a remixable CD. You read that right. This CD comes with sampling and remix rights. Strip off beats, vocals, instrumentals, whatever, and use them in your own projects.
Now, I ain't a sampler or musician, so the rights issues don't really affect me, but I think it's damn cool.
