You’re getting old. I’m over 60, so I can say it.
So are you dismissing shoe glaze and Dream pop as new styles? Also try Alicia keys or Taylor swift. Sure, they borrow from jazz singers, but they made it their own and they sound nothing like Ella. Same how rock and roll borrowed from the blues.
I will agree these genres are not life changing, not as big as the ones you mention, but none of them just appeared, they all took time to grow and develop. We lump Bach, Beethoven and Stravinsky together under classical. We may be too close to the changes in genres today to define them as people will 100 years from now.
As for hip-hop, I agree with you, I myself only put it on at the gym. And it’s not the same as rap as some believe. Hip hop evolved from rap. So you do have that in the last 25 years.
this is just a viewpoint, I am not a musicologist, just a lover of all music.
Jason I respect a lot of your input, but what you just said about rap-hip hop is what my Dad said about rock and roll 50 years ago.
