AI Generative music sounds pretty darn good to me present day ... here's an AI Mariah Carey singing a 1990s Michael Bolton song ... you wouldnt know it's AI by just your ear. If you were familiar with the song and Mariah carey you'd probably think or ask I didnt know she sang this song.
Still recognizable from some imbalance in higher frequencies which could also be due to the use or simulation of an harmonic exciter, and the usual "s" still sounding a bit fake, but yeah they made some pretty darn good progress lately.
