Is metal music mostly for introverts persons?

A music genre is not limited to any group of people. I do believe that that's a correlation between our listening behavior and our personalities but not like people with personality A listen to genre B.

I don't think what you said is true because most people don't even know what extrovert or introvert really is. Almost everybody is both extroverted and introverted just on different levels.

Steel and Bone is right. Introverts are not shy and quiet people who do not socialize. It's about how you energize yourself. Introverts need alone time after socializing. It doesn't mean they don't socialize or hate socializing.

No, though I am an introvert metalhead.

A lot of people don't really know what introvert means, and often confuse it with shyness or antisocialism, but they're all different things.

Introverts are just social in a different way - we'd rather have few friends with stronger bonds than lots of semi-friends. We tend to want to be alone to decompress after doses of socializing.

Anyway, metal is there for anybody who can truly appreciate it. For me, it's like oxygen or food. It sustains life.

Yes perhaps, most of the people I knew in my teenage years and 20's didn't listen to metal, and I'm quite introverted.

I wouldn't say it's FOR introverts though, as if that's the intended audience.

All of the kids at my school that wear metal shirts are loud and annoying

In my experience I've always found Metalheads to be extroverted but rather insecure.
