I wouldn’t call not appreciating death metal being “stuckinyourmindset”. I mean I like death metal but it’s a style of music that is simply going to sound absurd to most people.
Frink has the same mindset about Metal in general
I like a little Metal, but a very small amount.
Most people hate certain genres. It’s not an attitude or mindset (which makes it sound like I’m being unreasonable). I’ll bet you can think of a couple of genres that you can’t stand. Country?
I dislike certain genres sure but I would at least listen to some music from those genres before rendering a verdict. Just like with anime I have a strong feeling you wouldn’t make such an effort. Now if you did listen to a reasonable amount of Metal and didn’t like the music that’s fine because at least then you would have an informed opinion.
