I haven't listened to them in years, and I was never a huge Hollywood Undead fan, but they've changed a lot since I last heard them. I don't know about it being Muse's first big hit, though, because the first one I would think of as a big hit was Plug In Baby (that was the first one I think everyone you spoke to knew), but it definitely sounds very Muse-y. The chord progression sounds like a muse song, maybe New Born? I'm not sure - I'm not a huge fan of the band to be honest, but I'll have a look. Only album I have though I think is Absolution.
EDIT: Just looked up New Born - intro riff, second half - sounds a little like that, I would say.
