I'm sorry the proper title of the song is "Open Fire!"
No, the proper title of the song is "Feuer Frei!"

Anyway, my personal favorites are:
-Mudvayne - Dig (sometimes i listen only this song during my workout

)
-Hatebreed - This is now (or anything else from Hatebreed)
and of course, last but not least:
-Karate Kid soundtrack - You're the best
