There's a fundamental difference and that is music is the one profession where experience and practice does not equal better outcome. You can make the best track you ever made at 17 yrs old and then at 45 fire blank after blank, even with more theory, production knowledge, etc.
Its a complete paradox or human phenomenon, I don't know. Music is the hardest thing to make in the world, complex variables involving human psychology at minimum, plus some unquantifiable understanding of the arrangement of vibrations/frequencies, all of which within a shifting context of what society deems to be acceptable, relevant, cool etc. Its not about effort or desire or skill. Isnt that obvious? 100's of producers everyday trying hard for the best, yet we can see clearly its not happening.
