There's things I don't like about Gen Z, but most of it I understand the reason behind it. The not liking rock music thing is too bizarre though. Everyone liked rock music. If you were in grade school in the 2000s, you were liking music from the 70s, Pink Floyd, Led Zeppelin - through the 90s.
It seemed like every generation appreciated rock.
But I've heard that Gen Z does not like rock music. I don't get it. To me that's like "not liking apple pie"; it's such an American cornerstone that it's baffling.
I know a fair number of zoomers who don't seem to go for rap at all. I can't tell you what their specific musical preferences are exactly, but it's nothing close to rap or anything particularly awful/weird.
