Here’s a great site for finding “free” and legal audio to accompany any multimedia project. “Free music is music that is not managed by performance rights organizations (PRS, ASCAP, SOCAN, BMI, BUMA, JASRAC…). Artists choose to protect their rights through specific non exclusive licenses such as Creative Commons. ‘Free music’ doesn’t necessarily mean free-of-cost or devoid of any rights restrictions, it means “some rights reserved”. Artists define what rights they grant on their music through their choice of license.” — Jamendo’s FAQ
