Color me not surprised. As formulaic as modern country is, I have come to suspect that most of it was AI-generated, given the similarities of subject matter (cold beer, tight jeans, Mama's cooking, Jesus, tractors, dirt roads, pickup trucks) and replicated music patterns.
i would also suspect AI to come to dominate other musical genres, especially among those who aren't really that particular about depth and substance to their favorite music.
But I am optimistic that good human-generated music will always be with us. I've posted here before that my YouTube algorithm is always blowing up with new undiscovered talent.
