How can I get the audio from a music video? Just the audio and nothing else?

I'm doing a dance solo and I want the music from Michael Jackson's You Rock My World music video. Yes, they are different. There's sound effects and stuff when the dance sequence starts and I want to use that. I can't find it on LimeWire so does anyone know where I can download it online or... show more I'm doing a dance solo and I want the music from Michael Jackson's You Rock My World music video.
