I think music is the greatest art form that exists and I think people listen to music for different reasons and it serves different purposes. Some of it is background music and some of it is things that might affect a person's day if not their life or change an attitude. The best songs are the ones that make you feel something.
A game one of my sisters will play with me in my first year of being alive is called Good Baby Bad Baby. This consists of being told I am a good baby until I smile and laugh then being told I am a bad baby until I burst into tears. This training will stand me in good stead all through my life.
