I don't have to tell you that young folks have different priorities than you.
How many similar priorities are needed to enjoy a particular song? While not all music is for everyone, damn little good music is created for just a narrow target demographic. Really good music is timeless, and transcends artificial boundaries of age and "demographics".
The fact that there are some old farts who are so narrow-minded that they cannot recognize the quality in new music doesn't prove that the musicians aren't attempting to please those old farts. It just proves that those narrow-minded old farts are narrow-minded old farts.
This as come up many, many times in other threads. There are huge numbers of younger listeners who prefer to hear vintage (aka "classic") music than modern, disposable pop music. Yet back in the days when what is now "classic" rock was being recorded, there was also large amounts of disposable pop music being released and played on top 40 radio that few people want to hear today. Likewise, the disposable music of today has little appeal to those who prefer the timeless quality of classic rock music.
The problem is that there are old people who are so damn narrow minded that they can't tell the difference between modern "classic" music and modern disposable pop, so they assume that everything today is crap. But, since the suits who pick what modern music gets played on the radio have tin ears and rely on bogus testing techniques to decide what to play in order to appeal to their bogus ideas of what various "demographics" want to hear, most of what is on the radio today is disposable crap. The only way for the old farts to wake up and realize that the problem isn't that modern music is all crap, the problem is that the suits responsible for deciding which modern music gets played on the radio only select the crap.
And this statement, "So someone in their 30s is probably not singing or writing about subjects you're interested in" is probably the most asinine crap I've ever read. This year, those of us in our 60's are still listening to the outstanding classic rock written by songwriters who were in their 20's and 30's at the time they wrote their songs, even though both songwriters and songlisteners are now in their 50s, 60s, and beyond. How could it be that the songs that appealed to us in the 60s and 70s still appeal to us today if we now have a different perspective on life?
