The Power of Music

In the past couple of years, I've found music that has made me really feel. It makes me feel like dancing, feel happy and complete. Empty and sad. Calm and angry. It has brought out so many different emotions in me. And, I know my friends have found similar occurrences with music. It makes me wonder: could music save lives? Could music be so powerful, that just one song could change someone's life forever? Is it the lyrics? The intonation? What gives music that power? What songs make you feel?
