What percentage is the music in dance?

We all know that the focus of a dance competition is the dance. Obviously. But how integral is the music to the dance? Is the music why you dance? How much better is dancing to great music than mediocre music? Or does it not matter that much? Does the music have to be great to inspire you to new heights in your dance? Is having a great groove important to the dance?

If you had to express the percentage role that the music plays in your dance, what percentage would that be, and why?
