Recently I played Undertale. This game have a 10/10 OST, all of them are pretty good, but there was one of them that, really penetrated inside of bones. (jejeje)
This song if the battle theme of the final boss, Asgore.
The reason why this song is my favorite may contain some SPOILERS.

(Here you can listen three other song that I love of the game: Spider Dance, Megalovania, Death by Glamour)

Asgore is the king in the Underworld, not like the Hell, it's called Underworld because is under the World. He is a very kind monster, but cuz with great power comes great responsibility. He have to kill humans to take his soul to break the seal and go to the over world.

He never wanted this, he abhors the violence. but this is their duty.

This song have, or almost I can find it in, that feel. It's a sad song, a song of "I have to do but do not want".
