ccMixter is a community music produsage website that promotes remix culture and makes samples, remixes, and a cappella tracks licensed under Creative Commons available for download and re-use in creative works. Visitors are able to listen to, sample, mash-up, or interact with music in a variety of ways, including the download and use of tracks and samples in their own remixes. Most sampling or mash-up websites stipulate that users forgo their rights to the new song once it is created. By contrast, the material on ccMixter.org is generally licensed to be used in any arena, not just the ccMixter site or a specific context. The ccMixter site contains over 10,000 samples from a wide range of recording artists, including high-profile musicians such as Beastie Boys and David Byrne.
As a cultural phenomenon, ccMixter represents a direct response to what some say is the increasingly litigious attitude of organizations like the RIAA—one which prevents artists from appropriating elements of others' work for creative reuse in their own.
