ccMixter.org

It is official -- I am addicted to ccMixter.org, a shared music site where musicians from all over the world create colloborative pieces under the Creative Commons license. Artists upload tracks which are then available to remixers who invariably do something magical with the source material. The talent pool is vast and varied. Additionally, there is a kind community of artists who provide feedback and support. It's totally awesome. I can be found here: http://ccmixter.org/people/SackJo22 where my acapella vocal tracks are posted, along with links to remixes.
