We‚Äôre on the downhill side of 31 Days of Free Music month at Podcasting News.We‚Äôve talked about free guitar music, free classical music, free dj mixes, free hip-hop and even some brutal, unrelenting noise. We haven’t talked about using free music to change the world, though.

Electronica artist Ryuichi Sakamoto has launched a campaign to raise awareness of the risks of nuclear energy, Stop Rokkasho, which features a podcast with free music tracks and videos by Sakamoto, Thomas Dolby and others.

The Rokkasho-mura reprocessing plant in Japan’s Aomori Prefecture opened for testing on March 31st, 2006. Less than two weeks later, 40 liters of radioactive water containing plutonium and uranium were spilled inside the plant.

The Stop-Rokkasho podcast features music, video, photos, art, information and interviews to help spread the word about both the Rokkasho plant and the dangers of reprocessing in general. The podcast is a collection of free music tracks.
