If i were "ABOUT" to do something Badass, this would be the music playing!

P. S. The music i'm talking about starts at 1:17
It's a toss up between
Chicks Dig Giant Robots
Awesome Forces- The Aquabats
Nough' Said
when your evil by voltaire
Fatboy Slim - Weapon of Choice
or maybe
Sweatshop Union - Come Back
How about
Presidents of the United States of America - Peaches
Yeah, I like that one.
Anthem for the Underdog by 12 Stones, not so much bad ass as it seems but it inspires me to never give up and fight until its over even if your being humiliated at what you do. But I think the most bad ass theme is 10's by Pantera but I am not as big as a tank and speak only 5 words.
This badass theme
DBZ Budokai OST : The Battle With All My Force
Battle Metal by Turisas.








Depends really, if I had to do something truely badass
Light Up the Night- The Protomen

or I am comming back from a good party
The Good Times are Killing Me- Modest Mouse
http://www.youtube.com/watch?v=vaqY-BI1Mo8
I know I lose my indie cred by listing a Modest Mouse song that came out of one of their more popular albums, but it makes for an enjoyable ride home with the window down.
