Bored, so I found this random quiz. What Heavy Metal Genre are you?
You Scored as Thrash Metal
Other than non-metal and power metal being way lower than they should be, it's pretty accurate. Can't stand most death and black metal bands.
Also, 'NEW Metal' is not a thing, I think it's supposed to say 'Nu Metal.'
There's also this 80 question quiz that's a lot more thorough, though I don't know even half of the bands on there.
