Surely if genius is to maintain any usefulness as a word at all, it has to mean more than that the person didn't work with a big production crew or have a "primary collaborator", whatever that means. How irrelevant!

I'm not sure if this notion of "genius" helps people appreciate music or if it just worsens the idolising/othering aspect of it. If we are going to use the word, though, can we not attempt to reserve it for the uncontroversial candidates, like Art Tatum, for example.
