English singer/songwriter Ed Sheeran uses this heartfelt song about the really important things in life to close his concerts. Positive uplifting lyrics, a great melodic hook, and fun-to-sing harmonies make this a great pop selection that talks about music and the power of love. "We could change the world with a piano. Add a bass, some guitar, grab a beat and away we go... Love can change the world in a moment, but what do I know?"
