The new album by Italy's Canzoniere Grecanico Salentino is a "songbook" for the world. Pop songs are the soundtrack of people's lives. More than just entertainment, they make direct emotional connections to listeners.

Love and the loss of love, everyday and extraordinary experiences, joy and sorrow, life and death - good pop songs cover it all, and the best do it with melodies and rhythms so captivating that we experience them as "earworms" - music you can't get out of your head, and don't want to.
