AI music will fill the gap. The "song of the summer," the latest TikTok trend, and music that plays for department store ads, will be produced and distributed by labels, without the need of a particular artist whose image they have to worry about. How many times have labels, who invested a lot of time and money into artists, had to deal with the artist having an episode or scandal? AI eliminates that risk.
I think trying to avoid AI music will be like trying to avoid auto-tune, or digital instruments, or people mixing tracks in ways that are impossible to replicate with real-world instruments in real-time. It'll be common at first, harder later, and impossible/silly in the future.
