But I'll bet you anything, the average ear won't care. This music is already as good as what's produceable by humans, and will be available for a fraction of the cost without the licensing fees. Be ready to see it popping up everywhere—in cafes, restaurants, on TV ads, on your next spotify playlist. These soundtracks will become ubiquitous, and these far cries in communities like these will become a marginalized minority just like any technology that's been superseded.
Human generated music will still exist, of course, as the deep emotional ties that humans feel towards others (artists) cannot be replaced by this technology. But, there are massive use cases where that type emotional connection is not necessary (everything i noted prior, but also game & movie soundtracks, in waiting areas, tv shows, etc), where I would place a strong bet that this will eventually become even more commonplace than human generated music.
