Not their "best song ever" as I could name a few that are better but it's an interesting film clip, been done before though....
The Baba sound starts at 2:16
It's also the CSI New York theme song and I would have embedded a video of that but for some reason every one who ripped it off and downloaded it to Youtube seems to have disabled the share and embed section.
Have no idea why!?!?!?!?!?!
