Growing up it was metal all the way.
Then my tastes broadened out and I listened to more classic rock. Discovered that, far from being dull stuff for the old bastards, The Beatles were the best band of all time - that kind of basic trajectory.
Got more into indieish type music, but still always retained a love for anything heavy involving a guy growling about dismembering people, that kind of thing.
These days I listen to a lot of different stuff -rock, metal, alternative (which is a bit of crap description), electronic, folk, hip-hop.
I don't know what scene that places me in. I know that 95% of my t-shirts are music related. I suppose I'm a metaller at heart and I'll always feel comfortable in some sweaty venue, which reeks of BO, with some fella on stage roaring his head off, but I'll generally go to most gigs that I can go to, regardless of genre.
I think once you get out of your twenties, to still actively take an interest in music - in the sense of seeking out new bands, acts or sounds and going to gigs - kind of becomes a "scene" in and of itself. Most of the people who I went to school or university with, who would have argued passionately, at length, about the merits of one album over another, or would have thought nothing of crossing the country to see a random band don't have quite the same passion for music that they once had. That's fair enough. Other responsibilities and interests develop in a person's life over time. People have kids and marriages to think about, I can understand how they mightn't have the time to check out the new FKA Twigs, or whatever.
