Behold...the masterpiece that is Babymetal!!!

Take a teenage J-pop band (dance moves and all) and have them sing over some awesome near death metal and you get this. It's like a leather-clad, fire breathing, sonic unicorn. Somewhere in Norway, there's a death metal fan wearing corpse paint crying. The whole album is brilliant.

You just won the internet, sir.

I have a few friends that love Kpop/Jpop, they'll likely get a kick out of this.
