Part of the problem, nowadays, is what is pleasing to one person is not necessarily pleasing to a different person. Some people love classical but hate punk, some people love punk but hate jazz, some people love jazz but hate country, and some people love country and hate world music, and some people love world music and hate polkas.
All of that said, a study of music theory is (in my opinion) time well-spent insofar as it helps the soul with its unyielding query of "why." Your mileage may vary.
Music moves so many parts at once, different layers of brain and neural net I suppose, but also the beat of the heart, sweat and memory, smells --- could be tobacco or lavender ---the heat that comes up from the belly. All these cultures have all these quirky kinds of music, but they all have music.
I would be afraid of a world where all the music comes from AI. I would rather hear a squeaky little girl with an off-pitch banjo, than all the algorithm-produced perfection which, seems to me, comes from the deceiver and the seducer.
