Sting:

Why does tradition locate our emotional center at the heart and not somewhere in the brain? Why is the most common image in popular music the broken heart? I don’t know… I do know that “Lazarus Heart” was a vivid nightmare that I wrote down and then fashioned into a song. A learned friend of mine informs me that it is the archetypical dream of the fisher king…can’t I do anything original?
