The song "Gravity" was written and performed by Sara Bareilles for her 2007 album "Little Voice". It tells the story of her first real heartbreak from a relationship in high school with a popular sports star. Though they had chemistry and fell in love, he cheated on her and they broke up, only to get back together intermittently as she went to college. The song explores the inability to stay away from someone even though you know they may hurt you again. It has since been covered by several artists on shows like American Idol and The Voice.
