I just got a new IPod and wanted to christen it by downloading a certain song. Although my friend downloaded it as an mp3 file a year ago, the song is now impossible to find. Do any of you technical computer people know how I can take the music track from a video and download it as an mp3 file song? That's how it was done originally by someone else when my friend had originally downloaded it. I'm not looking to cheat anyone and I'll even pay $5 to get it(PayPal?), that's how retentive I am over this thing after searching for 10+ hours now and nothing.

The video is here
