[LAU] CC licensed music repositories

Sorry in advance for crossposting. I am creating my own podcasts. However I am concerned about how the songs and audio I'm using as background of my speeches is copyrighted. So I wonder which repositories of CC licensed music are out there, so I can download songs and use them freely as backgroud music in my podcasts complying to their license simply by attributing. Ambient style suits perfectly, but other styles could also be useful for me. Any ideas useful so thanks in advance.
