Humanity lost some things when it gained recorded music. It made the profession of performer less valuable, and diminished the number of performers who could make a living. But humanity got something very valuable in return — the ability to record and play back music. The same goes with the tradeoffs made for photography and motion pictures.

I see little value to humanity in tools that are able to generate an endless amount of music derived from existing music, specifically designed to neatly slot into the place of human artists. We gain little in return from that.

Some people will make an argument like, this lets people generate lots of low-quality music for use in elevators or grocery stores. Well, there is already a massive oversupply of completely free music which can do that. Do people pretend to not know this?

The other weak argument is that it lets people express themselves who haven't studied or practiced music. But, it doesn't, because the interfaces (text prompts or "upload an existing file") are designed to take the place of a human being given instructions for criteria to fill, as if they were a worker, not an expression of the person giving the instructions. If the person giving the instructions were expressing themselves, most of the AI tool would not be redundant. It's as expressive as telling another person to write a song for you with some instructions. Hardly expressive at all.
