The one part of the comic I don't think I've heard a single negative thing about, I cannot recommend Homestuck's vast discography enough. You might even find some familiar names among the music team.
A journey through Hell with intent to harvest blood needs a suitably intense soundtrack, and Hakita delivers in spades. I didn't think you could make metal breakcore listenable, but he damn well did.
Needing no introduction, Daniel Rosenfeld's gentle piano and strings complement Minecraft so well I can't imagine the game without them. Truly deserving of the title "soundtrack of a generation"!
