Soundtrack to a Battle Epic

The more I listen to "This Day We Fight," the first complete track on Megadeth's new-ish record, Endgame (now with more Roadrunner bashing, non-ironically reported on Roadrunner's quasi-official speech organ!), the more I think that Mustaine must have written the lyrics after watching Nathan Explosion pile up bodies Conan the Barbarian-style in the opening to the first episode of Metalocalypse - or after reading about the bloody, bloody adventures of Attila the Hun. A sample:

Bathed in blood up to the horses' bridle
It's death to retreat, there's no chance of survival

Whet with your blood, I sharpen my sword

No turning the other cheek like a coward
Come tomorrow I may lay down and die
But not this day, this day we fight!

Strip the fallen heroes, finish off the wounded
Collect the spoils of war and send them back dead

Pretty brutal, right?
