Well, music is art. Some of it is done for hire or commission. Most code is written for an employer or contract. Code written as art is an edge case.

For advertising jingles it makes some sense. For artistic expression, like... what's the point?

If the act of creating this AI music provides joy to them... I think they are artist

I used to release music that people listend to, but not anymore, now the only joy comes from making it for myself. Am I still an artist?

Is a scrapbooker an artist? If a scrapbooker is an artist because of what collage is, is a MtG card collector picking layouts to arrange their cards in the array of plastic sleeves you can get, an artist?

If the MtG card collector is not an artist does that mean they're bad and need to stop?

If the MtG collector only orders the cards for the joy of making a pleasant composition and does not provide any function like finding the cards faster or keeping them in good shape.

I think they are doing art.

If the main reason is to keep their items clean, as much time as they use doing the composition or how good it looks, they are not artist.

In my book, you are definitely an artist. Perhaps the purest kind, not that it's a competition.

If the act of creating this AI music provides joy to some, they should do it. I just have a hard time understanding that.
