Music ... Why is it such a passionate subject ?

Hi Lads, how are we feeling this week ? Me ? Well ... I guess I'm holding up ...
Last night, I had a huge fight about different musical genres and I felt bad because I thought I had a good and broad vision about the subject ... But at the end of my little predicament, I noticed, first of all, how stupid I was to argue about such a delicate matter and then that I was very mad at me for not being able
to accept my ignorance about new musical genres and its peculiarities ...
But two questions popped into my mind while discussing it: "Is music evolving to minimal beats and more complex electronic montages and am I stuck in time and cherishing a genre (rock'n'roll, in my case) which is practicly dead ?"
Well, I guess there's not a correct answer to the questions but there's a way to understand what kind of moral problem I've stepped into yesterday ... And the person with whom I was arguing opened my eyes to it ...
The thing with music is that no matter which genre or even who's singing or producing what, it has moods, messages and the most important thing, a time to get into your skin and mind ... And that's a major point when I'm listening to the electronic music because I guess (and now after thinking about it, I'm pretty sure) that I'm not ready to find the beauty and the refinements that this genre needs while processing it ... And this person made me understand that while we were talking about it yesterday ... Most of people do that while making their personal musical choices ... They pay attention to every little exquisite hidden pleasures that a specific genre will give to them ... Like the fun, diverse, grooving beats in electronic music for some people ...
In my case, I pay more attention to the rock'n'roll genre because I know every little nuance and corner of its musical and moral construction ... And also because it's my music genre of affection ... I feel cousy with it ... I feel fulfilled by it .... It makes me feel bigger than life ... To sum it up: no matter what you're going to feel, write or even choose as a musical genre, it doesn't care because it's a very private choice and those kind of decisions shouldn't be the most complicated ones ...
I guess what I'm trying to say to this person now is sorry and she's right about her feelings towards new musical frontiers ... I've completly forgotten this side of music and maybe this is what new music mean to people nowadays ...
And come to think of it, making decisions is hard enough on your knees ...
Imagine people criticizing your personal choices such as music, movies, people you love and so many other stuff all the time ... It's too complicated and annoying ... But it's worth living and understanding it ...
Like with music and my girlfriend for me, for instance ...
Cheers and rock on, Guys ...
