I found this page: http://www.econore.com/mega-rick-untitles-creative-commons-action-pack-download/
There you can download a zip with 15 songs under a cc license. they encourage you to remix them.
Since this 15 songs are all pretty noisy and weird stuff, I was wondering what anyone would make out of them…I couldn't imagine anything.
That's why I'm asking you guys…could result in either edgy stuff or total bullcrap :-)
