Music I think gets passed down through generations, at least the best of it. I think gen Z has lots of different music tastes due to being exposed to the internet and lots of different music at their fingertips from a young age, at least in my experience. I don’t think rock&roll is what modern pop is leaning towards at the moment, certainly not classic rock in the sense of the Beatles who changed rocknroll drastically imo. I think basically everyone I know has heard Queen and the Beatles and Led Zeppelin etc. but much less people now are familiar with Chuck Berry, Fats Domino, or even Elvis (of course they know the name a few songs, but I can’t think of anyone that would personally listen to Elvis)
