I don't care what anybody says, the thrash break and solo of "Pull Harder" kicks ass. (and if it wasn't a Trivium song, nobody would disagree with me). Still the first verse of that sounded dead on (parody wise).
As for the Pantera one, I know the lyrics way too well to misinterpret it.
I listened to three Babymetal tracks...sounds like Chun Li getting butt-fucked by Andrew W.K. That's not something I ever wanted to hear.
