Your comment implies that there is an existing piece of music, which can subsitute the generated music. While subsitutability varies from person to person, your original statement implies for me that each generated music has an accompanying original music that you can listen to instead (of which it was "stolen" from), since it is similar enough. I think we both know that that is not the case.

I know that you likely intended to imply that you can subsitute the aformentioned AI music with an existing piece of music of the same genre, but that is not a view shared by all. Sometimes the generated music scratches such a specific and personal itch, that it cannot be replicated by something in the same genre.

A better counterargument to your original comment would be "It is not an exclusive situation. I can listen to and support both generated music and handcrafted music at the same time. They both contain music tracks that I like."
