The Secret To Great Art and Music

What is it about organized color and organized sound that people are so drawn to? I'm speaking of art and music, of course. All of an artist's years of study and practice, of learning structure and theory, and history, of studying the masters, of experimentation, of viewing/listening to other artists, still doesn't make for a great artist/musician. The most vital ingredient to great art/music is still missing. Why is it that we can listen to two different performers play the same piece with equal amounts of skill and years of study and yet one fills our hearts, and the other doesn't? The same can be said of painting - we can appreciate the level of skill and technique of one artist, but the other one makes us want to be INSIDE the painting, and we've forgotten all about looking for levels of skill and technique. Mozart said it best when he said "Neither a lofty degree of intelligence nor imagination nor both together go to the making of genius. Love, love, love, that is the soul of genius."
