Occam's razor. Trust your ears before you misapply a theory like "cognitive dissonance."

Respectfully, I think we must use this theory to 'shoe the other foot.' Cognitive dissonance is a psychological phenomenon which refers to the discomfort felt at a discrepancy between what you already know or believe, and new information or interpretation. It therefore occurs when there is a need to accommodate new ideas, and it may be necessary for it to develop so that we become "open" to them.

Trust your ears before you trust theory that says you shouldn't. The music comes first, theory much behind it.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
