This is a very good point. I listen to a lot of great "new" music, but I do that by listening to oddball radio stations (like KCSM San Mateo), going to music festivals (just got back from the Sicily Jazz Festival in Italy), and "new music" events (like the Cabrillo Festival of Contemporary Music https://cabrillomusic.org/ ), and I play the piano with amateur groups and in amateur recitals.
It takes a lot of work, but all I hear is new music, or fresh takes on old music. But sadly, the audience for this is either people like me (men 55+ and some women) and kids who are music majors. There's little in the middle.
I think the average kid who simply followed pop and rock back in the 70s knew more about "music" than the kid today to whom it's just a branding, or a backdrop for a TikTok. They don't listen and pay attention. Pop culture doesn't resolve around music anymore. There's too many other things (games, social media) to worry about.
