I'll challenge the old "musical tastes are carved in stone at a young age" theory. And I'll go as far as to suggest that we truly are currently at a low point in the musical landscape.
Most of my favorite music is stuff that came along long
after my impressionable years. Yes, I still enjoy classical music and traditional jazz and 70's prog as much as I did when I was young. Even more so now, because I hear more in it that would have gone over my head back then.
But I also like folksy stuff that I would have dismissed when I was in my 20's. I am a late-blooming Rush fan. I enjoy (some) modern Country when it doesn't try to be formulaic. I even appreciate some of the 80's hair bands now. I listen to a nightly radio program that features all blues, discovering that that genre has a whole lot more creativity going on than I once presumed. Ditto for Big Band and Swing.
My musical palette literally spans more decades than I have been alive. And most of it discovered (ior re-discoverd) during my adult years.
But the last 10 years have contributed very little. It all seems terribly derivative now. When Kanye West is hailed as a genius, it would seem the world's drunk some kind of mind-numbing kool-aid.
