This is an interesting essay covering a lot of issues surrounding generative music. If you've read a heap of Brian Eno interviews then most of the subject matter is more about whether the music industry would recognise generative music as music but it's a great collection of stimulating ideas.
I've been wondering when there will be a program that registers what the user/s prefer (breaks, ambient, dnb, etc.), what time of the day, what the stress level in their voice says their emotional state would be, etc. and creates bespoke background music according to their previous preferences.
But I guess the real issue is that generative music is yet to become as intricate and accessible as pop music because that is what is marketed to the 'mainstream' as 'music'
