Moved to Tears

Why are some of us drawn to songs of defeat and broken dreams? What is it about them that strikes a chord with us? Is there some lost lost, forgotten hurt or disappointment that causes the sentiments expressed to resonate within us? Could it be the language of such songs is stronger, more interesting than those found in songs of joy? Perhaps we enjoy being moved to tears, feeling the heartbreak of others, being consoled in the fact that others has experienced such things.There must be something or else the writers of these wouldn't be so prolific.
