I remember first playing this part of the game on the PS1 a few months or so after getting it for my birthday in 2002. I knew when I heard that port's version of this tune that this was where the game's difficulty was REALLY going to ramp up. I was right.
"Those fools are on their way, they'll rue the day they came my way I'm Chaos!!! In the flesh... The Fiends compare to fleas compared to me, it's great to be Pure Chaos!!! I laid Erdrick to rest... And one by one you'll die by my hand... Oh look what I've become. This fantasy is far from final... The worst is yet to come!!!" Those who know... know.
