You've got it flipped. I'm saying that having a deep knowledge of theory isn't what enables you to make great music. I am also saying that most working musicians' knowledge is extremely limited and that absolutely makes their work outsider art. That's not saying that anyone should go to conservatory (anything but - if you want music ruined for you by all means go), but yes probably every musician _writing music_ should improve the knowledge of their craft.

I used to work in the music industry. I think your beliefs about writers' knowledge of music theory are way off.

That's cool, don't really need your validation.
