I play some instruments (for fun) and take music seriously, though that phrase implies less pure enjoyment than analysis, it's really not the case for me. I get extremely strong dopamine hits from simple meledic "hooks"--as they are called--and stronger and deeper emotional involvement also with complexity and challenges to melodic expectations. For me, popular music has gone wrong (not really talking any specific time frame here) when it only meets simplistic expectations, as I think the key to how music rewards is both expectation and surprise. This problem has advanced over time and created a lot of listeners who have developed a kind of culturally induced musical agnosia. They don't seem to even hear music with a lot of different notes, chords and time signature changes as music at all. Rick Beato and others have examined this, and I hope the pendulum swing of cultural shifts moves back the other way again in time.
