lukewarm take, Dethklok, Baby Metal
In the first Ep of Metalocalypse, Nathan Explosion says the goal of Dethklok is to male everything metal. Coffee, door to door sales, college graduation ceremonies, all metal.
Along those lines, Baby Metal is taking Japanese Idol Pop and making it metal, and I can't understand why people would give them a hard time.
Then I remember that the internet is 90% assholes and yeah, it all makes sense now.
