"Overjoyed" is about a happiness so complete it becomes its own kind of overwhelm. Stevie Wonder recorded it in 1976 as a ballad about a man who has found something he did not dare to hope for. He is not just happy. He is overjoyed, past the point of simple happiness, into a territory that feels dangerous because it matters too much. The song understands that deep joy is not safe. It carries the risk of loss built in. The higher the joy, the harder the potential fall. Stevie sings like a man who is willing to risk the fall.
