I think there's a difference between music that people will cherish for decades to come, and music that will sell in the short-term. This isn't even me being an "old man yelling at cloud," you can look at what was charting in the 80s-90s and recognize some songs, but others just got lost to time. They were fine, but they weren't special.
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.

These are 2 cases where you absolutely need a personality to go along with the song. Department store ads are probably already AI.
