Metal To the Core?

You find weird things on Twitter sometimes. Yesterday, I came across a Tweet from ZodiacFacts that said something to the effect of "Leos love heavy metal and hard rock." Basically, the gist was that Leos like music with passion.

I'm a Leo and this got me to thinking: is being a metal fan so ingrained in a person that it is just in their core? Put another way, was I destined to be a metal fan versus someone who loves country or classical or jazz?

There probably isn't an easy answer to my question, but I do think people are naturally inclined to like one thing over another. I mean, I was a metal fan in fifth grade. I'm an only child, so I didn't have older siblings to share metal bands with me, which I know is a common experience for most metalheads. So what drew me to metal? It had to be the rhythms, MTV and the fact that my parents like rock music, right? After I realized I liked rock and metal, it didn't take long for me to search out new bands on my own. Now, here we are some 20+ years later. I can see myself getting into other forms of music for sure, but none the way I feel toward metal bands. I can't see that changing ever in my entire life.

This must be pre-determined and cellular, yes?
