I suspect that AI generated music will be widely produced and consumed in the same way AI movies will largely be used for say commercials or cutscenes, AI images for commercial illustration, and LLM text for content writing; interstitial filler material that is obligatory but no one really seeks out. So you’ll hear royalty-free AI-generated muzak when you’re on hold watching network TV show procedurals/sitcoms, meditation apps and low-fi hip-hop beats channels. When there needs to be sound that you’re not actually focusing on.
