In my view, attempts like this misunderstand much of the point of music. That is, to communicate aspects of human life that are deeply interwoven with facts and experiences outside of the music itself. I don't see how any of that will be possible before we have some kind of general AI, and in the meantime I think these attempts will continue to be semantically empty, even unsettling in their emptiness.
Image and sound are ultimately related to feeling ... and it is those feelings that give us humanity -- not the ability to think and manipulate symbols (though that was not apparent to me until this current AI revolution)
