Creative Commons, DJ Vadim and BBE have released all original solo, individual instrumental and a cappella tracks for DJ Vadim’s “Soundcatcher” album under an Attribution NonCommercial license.
This is cool because remixers and producers can freely sample these audio sources to create their own (non-commercial) works.
If you are a producer, go download the audio sources from ccMixter. Then, I would encourage you to create an account at ccMixter, and upload your new tracks so others can check them out.
