Time For Punishment: Definately Kickassery.
Okay man, seriously. I heard this song on the game 'Light People on Fire' and I couldn't resist. Checked the end credits, and looked all over a few music download sites - no where. I admit, I was sad.
Checked generally, and found it here on Newgrounds. Gotta say, this is one of the most impressive works I've found on here. Downloaded, 10'd, and complimented, man. Well done.
