Yikes, ya beat me to it. I wish I could like your comment 20000 times. :c
The World Revolving and Your Best Nightmare/Finale are my jams.
(Also Vs. Lancer and Spear of Justice.. and Metal Crusher.. I have too many favorites)
My favorite boss of all time is shadow link/dark link
and my second favorite has to be marx from super smash bros ultimate
my third is flowey from undertale its pretty easy to beat but when you die it just laughs at you and forces the game to close
Arvis' theme from Fire Emblem. While it only plays once in the game, you know **** is about to go down when the character walks on-screen in the Prologue chapter and has this theme playing over a foreboding monologue.
