You don't usually call the audio engineer a musician though. The fact that you "want a string section" is the important part. Art is communication, if you fuck with the AI until it communicates what you want, that can be art, as long as you're not trying to pass off that the fake brushstrokes contain any meaning. If you learn all the right prompt words to make it "good" and then Photoshop it to fix all the telltale AI glitches but the only idea being communicated comes from 6 random people on Deviantart smashed together, that's not art.
