I'm '80's Metal. That's what I grew up with along the early "grunge" of '91/92.
Everything else after that has been a bit Blah for me. Korn and Limp Biscuits etc always bored me. So does black metal. I think it sounds like dogs barking but I also don't care for the ultra mega melodic metal bands like Kamelot. Saw Sonata Artica with Firewind & The Agonist a few years ago. Almost fell alseep standing up. Dio, Priest, Maiden, Metallica, Megadeth, Anthrax, Slayer, Helloween, Overkill, Metal Church, Suicidal Tendencies etc...Those were "my" bands alongside Soundgarden, AIC, Jane's Addiction and those types too.
So to answer your actual question.....I don't have a fucking clue.
