Music to fight to.

[SirDeadly]

If no one has already said it (shame on you) Eye of the Tiger!!!

 

[The Maddest March Hare]

These do the trick for me:

Spoiler: P.O.D.

Spoiler: Disciple

Spoiler: Sybreed

 

[Snipermanic]

Both of these have come on shuffle during really appropriate times during my gaming killin'

 

[Soxafloppin]

This of course!

Do i win?

 

[Rakkana]

Let the bodies hit the floor.

[Mechsoap]

or the start of this song

 

[Haloperidol]

The Zero Punctuation full theme song.

 

[someonehairy-ish]

Let the bodies hit the floor by drowning pool.

[FieryTrainwreck]

Warning: punk cover of a Method Man song, which means a white guy will be using the n-word. He also flashes his wang briefly at the start, but it's covered by a blue circle. Plus that chick totally told him to.


You can't surpass the intensity of this song. You can only hope to match it.

 

[PatrickXD]

[nick n stuff]

Safety Dance by Men Without Hats

OMG Someone else knows this song!!! But... why fight to it...

 

[Valkyrie101]

Anything by Manowar, particularly Call to Arms, appropriately enough.

 

[Eggsnham]

This is good fighting music. At least it makes me all fighty-jumpy.

 

[Snarky Username]

Easy.


Great for both fighting and dancing!

 

[Sir Kemper]

Megadeth's Duke Nukem theme:


Also depending on the situation this might also work:


Still, it pales in comparison to the Duke Nukem theme.

 

[Flamezdudes]

Muse - Knights Of Cydonia

Spoiler

Slipknot - Duality

Spoiler

 

[Jackalb]

Barbie Girl - Aqua.

Or as the OP said MK theme, fail that then Breathe/Fire Starter/Smack my ***** up - Prodigy.
