That's funny. I was having this similar discussion with my 16 year old niece, and I was asking her what she's been listening to as a 50 year old trying to broaden my musical horizons. She pulled out her Spotify and shared some of her playlists with me, and I was astonished to see that most of the music that she had been enjoying was produced in the late 1960s to the mid-1980s. We had a good laugh about it, and bonded over some of the classic music that I love that I was suprised to find that she loves. There were some modern things interspersed, and I did learn about some new artists and experimental genres. Seems like a clear example of the Law of diminishing marginal returns in the cinema and music industries in Southern California — leading to those industries collapsing. AI and generative crap being a big evidence point for the argument.
