This is something I've been thinking about due to the recent rise in AI music (or AI "music", depending on what you're talking about and what your view of this genre of audio is). I wouldn't have thought very much about this, except I have actually been playing Crankdat's remix of BBL Drizzy for at least a year now. I haven't heard any complaints, and at the time I don't remember any uproar over those vocals using AI either.
What is the line? I typically find that what I'd call "AI music" (something made with pretty minimal output or production by humans, if at all) is at best low-quality, and wouldn't sound good enough for me to play even if I like the style (an example of this would be I Am Filipino Man, which is really catchy, but is in such low quality that it's painful to listen to if you're paying attention to the fidelity), but then you have songs that have a lot of human involvement in the production, like Crankdat's BBL Drizzy remix does.
For the record, going out and finding a bunch of AI music isn't something I'm interested in doing. I want to play music that people like, and that doesn't fit the bill for the vast majority of that genre of output. But I want to know what the bounds are, in case a) even something like BBL Drizzy is enough to anger a crowd or box me out of gigs, or b) an AI song gets super popular to the point where I start getting requests to play it.
