"Soul" music

from Marin Williams' review of Ornette Coleman's album, 'The Shape of Jazz to Come' - published in 'The Jazz Review':

"It is probably impossible for Ornette Coleman to discuss music without sooner or later using the word love and he has said, 'Music is for our feelings. I think jazz should try to express more kinds of feeling than it has up to now.' He knows well, then, the source and reason for his music. He also knows that he does not 'own' it himself, nor 'invent' it, but is responsible to something given to him. As is so necessary with an innovator in the beginning, he is not afraid to play whatever his Muse tells him to play: "I don't know how it's going to sound before I play it any more than anybody else does, so how can we talk about it before I play it."

Do great musicians have the propensity for the creation of great music residing within their individual? Or, are they just better in tune with and able to tap into a universal Muse - translating messages from the metaphysical into musical sound? In other words, does Keith Richards exist as a musical genius from his own side or is his mind just more conducive to being a vehicle for heavenly sound than the average person? Is this musical genius an exclusive ability or do we all have the potential to be conduits for pure soulful tunes?
