You know that CC licensing is reaching far into the music scene when you have a genre-specific region based podcast like the NY-NE Regional EDM Showcase. In yet another example of what is enabled by CC licenses this show features “original EDM tracks from independent musicians within upstate New York And Western New England” all CC licensed.” (mission statement). The show itself is licensed under a Attribution NonCommercial NoDerivs and each song in each song in the “Commute-Size” mixes are under various CC licenses.
The latest is Commute – Size Mixes Vol. IV – Breakbeat with previous volumes specializing in Trance, Progressive and DnB.
If you live in the right part of the world, make the right kind of music and of course, license your music under CC, you can even submit files directly (terms and instructions here).
