I'm probably gonna sound boring as hell, but for me, Layla, Derek and The Dominos...

Hmmm....anything that X Japan does.

Art of Life, Tears, Stab Me In The Back - it's all insanely epic!

I have to agree with Raining Blood by Slayer.
It makes me want to go spear people in the jugular.

suicide note pt.2 by pantera

may have already been said, but cast down the heretic by nile.

beginning to end of that song is a speed fest. george kollias is a BEAST, i have no idea how he can play that fast for more than 2 seconds or so.

I don't think it has to be heavy to be intense. Janis Joplin's "Ball and Chain" does justice to this very fact.

any converge or godspeed you! black emperor song

Is it crazy on my part that I think Godspeed gets boring?

Jayhawker - Scale Model Failure
Unsane - This Stops At the River
Unbroken - Fall on Proverb

Its kinda hard to not do so, considering most songs are 20+ min opuses. There's probably only one or two godspeed songs that hooked me all the way through.
