Combining different Creative Commons licenses in a DJ mix

The chart below should give you some assistance in figuring out which Creative Commons license you can use on your mix. Some of the licenses just do not, as practical matter, work together.

The green boxes indicate license compatibility. That is, you may use the license indicated in the top row for your DJ mix. The blank rows for the by-nc-nd and by-nd licenses indicate that derivative works or adaptations are not permitted by the license of the original work, therefore you are never allowed to re-license them.

Fair use note: CC Licenses do not change, alter, or modify fair use rights. You may still use fair use rights to incorporate CC works for any qualifying purpose.

This chart is not a substitute for obtaining your own legal advice, nor should it be relied upon or represented as legal advice.
