In his book 'This is Your Brain on Music', Daniel Levitin, a rocker-turned neuroscientist, explores the connection between music and our brain, providing some interesting insights on why we love the music we do. In particular, Levitin helped me understand why Stevie Wonder, who made his way on to my soundtrack as a pre-teen, was still on my soundtrack during my 30's, the decade of launching a career and learning to mother. He writes, "teenage years are emotionally charged years of self-discovery. Because of the emotional component of these years, our amygdala (the seat of emotion in our brain) and neurotransmitters (transporters of information from the brain to other parts of the body) act in concert to 'tag' these musical memories as something important." What kinds of music and which artists did you love as a teenager? As an adult, do you listen to similar music?
