Music is a such a human thing, that getting an AI to create it, really kind of bastardises it.
but this... I mean I dunno
I like some midjourney art more than a lot of "real" art
At the end of the day it's humans that will use the tool and combine it how they see fit and it's humans that will decide whether it's any good or not ...
If aliens come down tomorrow with "superior" music, I guess it is humans who will be bastardising it. Stop gatekeeping :)
