They've been my biggest guilty pleasure for a long long time. They got stupid with The Black Parade but their new album is actually really good after you spam listen to it five or six times.
My favorite song from it is either Bulletproof Heart, Na Na Na Na, or The Only Hope For Me Is You. I just do not like Sing at all. I've tried to listen to it a few times but every time i end up skipping near the middle.
I mean, the Black Parade isn't a bad album but they over did it by a lot. That and Teenagers is just about the most annoying song ever imo.
