I know a lot of people are going to think I sound fickle, but yes, I completely understand how you feel.
Music is pretty much my life. I play three instruments, sing, go to gigs every weekend, spend the majority of my free time writing music, playing music, or listening to music, and I have a record/cd collection that could rival my local record store.
Because music had become such a large factor in my life, I found I couldn't relate to those who didn't care about it. I love rock music, it's my main genre of preference... though I also love French waltz, Irish folk, jazz, the list goes on! Anyway, I gradually ended up growing apart from those who were into mainstream music, because they just didn't get me anymore. This is the reason I usually date other musicians, and I now hang out with the school metalheads and punks (though I'm my school's lone Mod).
That said, I have lots of friends who don't care about music. However, it is a barrier that prohibits me from getting as close to them as I would to those who share my interests. Maybe you just need to make some new friends who like your music? There's absolutely no reason you can't be friends with both groups of people, you'll just connect in different ways.
I promise, we sometimes look intimidating, but... metalheads, punks, and even us pretentious mods are usually pretty nice.
