No other group compares, they listen to nothing but metal, some classic hard rock and punk at most, but that's it.
If you ask them about any other music outside of those genres they are clueless, they don't know jack shit about it; they'll simply say some stupid shit like "eewww I don't like it metal 4 life".
The rare occasion they like something outside those genres is usually shit, they are genuinely incapable of recognizing good music outside of metal, their heads are deep fried for listening too much noisy garbage music.
They even have the ego big enough to gatekeep metal, as if adding something they don't percieve as metal into their shitty music taints it, what a joke.
Metal music fucking sucks and you are genuinely fucking stupid if you like it, you are a lesser being, a troglodyte who deserves to be discriminated by society.
