Ahhh! Battle of the Immortals, that's it! Thanks so much haha. My mind can rest in peace

Disregard ALL of the bugs and whatnot this fight brings! I'm just wondering if anyone knows the name of the music of Soa's fight. I reallyyyyyy want to know and it's killing me that I can't figure it out! Makes the fight soooooo epic even though I've wiped on him on HM countless times due to god forsaken bugs, ha. EDIT: "Battle of the Immortals" is the song name, thanks for the help.
