I only buy CC BY and CC BY-SA music. Some of these albums are great listening music (see Marc With a C, Kellee Maize, Lorenzo's Music, Myuu, Professor Shyguy, et cetera), while other albums on this page are better for use in projects (see Chris Zabriskie, glitched puppet, et cetera). All of it's legal for reuse, remixing, and resale. Free culture is just awesome like that! Copyright is censorship.
