From the first heartbeat to the last breath, human life is filled with sounds, melodies and music. While some bring forth memories of childhood, others play a part in constructing a teenager’s or young adult’s identity. Music is almost always involved in rites of passage, whatever the culture: graduation, weddings, funerals, just to name a few milestones of the human experience. Add to that all the songs we love and that remind us of certain events in our lives.
