"i snap your trigger finger in six spots'

Or, you know, the whole part about the kid raping his own mother....

raining blood by slayer is ****in intense. haha

down with the sickness by disturbed can get you fired up as well

its not the loudest song ever but counting bodies like sheep to the rhythm of the war drums by a perfect circle is intense

yeah
you know..that too

most intense song? the theme of mortal kombat. Lol.

seriously, it's gotta be raining blood by slayer. never gets old and it's always intense.

I have to agree with all those who said Raining Blood.

But, there is one that is of equivalent intensity (even though it's a punk song)

Nazi Punks **** Off by the Dead Kennedys.

It's literally a 1 minute punk **** off telling nazi punks to, well, **** off. lol

The Great Southern Trend Kill by Pantera.
**** yeah!

the most intense songever is san fransisco serenade by tom waits.
