You're right, which is why I (as a music nerd) have gone out of my way to ensure that it's more than that. In a nutshell, here's why, despite every reason not to, one could still believe me.
When I as a youngster had to defend hip-hop against my parents, I was able to reference the music itself, see, this comes from that tradition, this sound come from here, roots in African and Black American traditions, this rapper is actually a saxophonist and adopted his style from jazz etc. etc. Citations and sources and the like.
As I've found/seen in entirely too many music conversations today, the kids can't do that. As in, if I'm like "okay, this guy who sounds like he's JUST mumbling, what am I missing here? I'm open minded and used to these conversations, go."
Crickets when you get to this level. They can no longer rely on "But music always changes, why do you hate young people, blah blah."
