Very simple this one:
Megadeth - awesome band (If you don't know them and you call yourself a fan of metal smack yourself in the face at least once for me)
"A Tout Le Monde (Set Me Free)" - my favorite Megadeth song.
"A Tout Le Monde" was actually originally on the album Youthanasia, but was re-recorded with Christina Scabbia, the lead singer of Lacuna Coil, and re-titled "A Tout Le Monde (Set Me Free)" for the latest Megadeth album (until the end of the year), United Abominations.
I've been finding my videos at metalvideo.com, which is a great site for finding new and old metal music videos (seeing as youtube is so watered down with crappy cell-phone live songs or stupid people who think they can nail a solo), but when you embed it onto another page the video player is so small, it's rather annoying. I assume it's to encourage people to make it all the way to their site, but it is still a pain in the ass.
If you want to see it full sized go to Megadeth - A Tout Le Monde
