I've only heard the single "shut your mouth" and liked it enough to download it!
I remember watching this lame show we got in Canada called Loud, which supposedly plays metal (rarely), and I saw this video, and I'm like "who the fuck is THAT? I'm sure I've seen that guy before... looks like he's from some Swedish metal band. Nah, he doesn't sound Swedish..." Sure enough, I went and checked my Total War CD (well, mine's only called War, but I hear they're called Total War now) and lo'and behold it was Peter. Fuck, I had to check twice judging from the complete difference in musical sound and ideology, but I still like Pain. If I ever see it at the store, I'd pick it up.
