There's a fair number of ai generated 1.5 hour or so collections of blues songs on YouTube, and some are actually pretty decent. I suspect the human in the loop guides the lyrics to keep them sensible and the voice from being too muddled, as there's plenty of lower quality stuff too. Same goes for a variety of instrumental stuff.

I hate it, and I hate liking some of it, as it is easier to find than quality human produced stuff in some styles and I'd prefer to support analog over digital creation.

With that said, there's a blues AI cover of gangsta's Paradise that is pretty sweet played at 90% speed. Again, I wish it was human performed, and I'm continuously conflicted about it.
