I think the age thing you talk about is a meme from the 50s or something, it hasn't applied for decades.
I just think there really is a lot of crap around now.
And unfortunately we may not get clarity for many decades.
But I think it’s worth thinking about what makes a piece of music classic? Why will it stand the test of time where others don’t.
And when producing music is easier than ever, does the proportion of good musicians increase proportional or do we just get more rubbish?
All nostalgia is a longing for youth.
I agree with Beato's angle, but it needs some expansion. Twenty years ago the music industry was cut off from its main revenue source by internet sharing. It has somewhat recovered through streaming but the money they spent on artist development has not. Why?
My speculation—combine the continued availability of classic acts (hello never-ending copyright) with the deluge of the cheap, mass produced content and there's just an incredible amount to choose from. It should be cheaper just from an economics standpoint, and since profit is down that necessitates less investment into excellence.
Also, all the good pop chords and melodies are probably already taken as well, the music is pretty simple.
The other angle to the problem is discovery, and that makes it very hard to get noticed. This article was pretty great on the subject:

To get back to an older era when we were younger... I remember iconic albums/singles dropping every single week in the eighties. The machine was incredibly well-oiled and running. Today I hear something big maybe once or twice a year. Part of that is the discovery problem I know-radio and mtv were killed by the internet star.
How to invest in quality, and how to make people aware of it?
Social media can be used to spread music like radio/CD/MP3 used to, but it isn't as effective at that task.
I'm not sure if this is good or bad. I mean, kids back in the 70's & 80's got relationship advice from random song lyrics heard on the radio, a horrible way to make life decisions. Now kids have much better access to information & advice so who's to say that the decline of music is an entirely bad thing? We'll see.
Thankfully, they are also just as disinterested in social media.
Is getting relationship advice from TikTok and Reddit actually an improvement? Seems like the falling marriage and birthrates suggest otherwise.
