Ah, come on the themes are dope haha. Though I wish there could be instrumental versions of them. There's a very awesome groove near the end of Blake's theme.

To be fair, Yang's I Burn is a huge meme since it comes on whenever she activates her semblance/gets low enough for her to go into install, disrupting the theme it played before that MvC style, wouldn't be surprised if a lot of people dislike that song. I do like all of the RWBY themes/songs though, imo they're good, plus it shows how far the characters came in the show (Weiss and Blake specifically).
