Can you imagine your life without music? It’s almost impossible. Whether we are cruising in the car headed to the beach on a hot summer day or listening to muzak at a doctor’s office, we are constantly surrounded by song. Makeups, breakups, parties, hanging out with friends, singing along with our kids, or caroling a Christmas tune—music stamps nearly every aspect of our life. Much in the way a killer soundtrack accompanies a movie, most of us have songs that accent each phase of our lives, melodies that instantly bring us back to specific moments or memories when we hear them even years later.
