I recently finished Francis Schaeffer's "How Should We Then Live?" and found his conclusions quite timely, considering the book is approaching its 50th anniversary. The latter half of the book specifically dwells on the effects of postmodernism on culture, especially the arts. Watching Rick Beato's criticism of modern music, I can't help but notice how eerily similar it is to Schaeffer's criticisms.
Personally, I've struggled to understand whether I'm suffering from nostalgia or if the era of good music is truly coming to an end. I wasn't able to afford college when I was younger, but I did have an opportunity to take a university level class on music appreciation later in my life. It's what still has me going to the symphony every year. Perhaps if such courses were more affordable/accessible, we might seem some improvements in this area?
