"Mobygratis.com is a resource for independent and non-profit filmmakers, film students, and anyone in need of free music for their independent, non-profit film, video, or short film"
Moby explains: "Well, the music is free as long as it's used in non-commercial films. When the music is used in a commercial film, any money that's generated goes to the Humane Society, so I get nothing."
