I don’t ...
but yes, most people get "stuck" on the music they listened to from about age 15-22. Seems very limiting. It possibly has to do, at least somewhat, with personality types. I’m a Sigma (I’m sure people have heard of Alphas and Betas, but they may not know there are also Sigmas, Gammas, and Omegas ... and some researchers might include Deltas). Sigmas are never standing still when it comes to interests and curiosity. However, Sigmas are only 6% of the population. The vast majority of my music library is 2000 to now, even though my "stuck" period should have been the 70’s. I believe, like with most things, in general music has greatly improved since my "stuck" period. Again, in general, instrumentalists, singers and songwriters are more talented, and have built upon the foundation of the previous artists. The one thing that is lacking is originality. There are no more Beatles or Elvis Presley or Led Zeppelin or Van Halen or *Yngwie Malmsteen popping up.
Also, some people seem to think that new music is all pop, rap and hip hop. But there are tons of new and old genres available, and many of these genres have morphed into better versions of themselves.
* Non-musicians probably won’t know Malmsteen, but 40 years ago he caused a seismic shift in the way rock guitar is played that continues to this day.
