Bobby McFerrin - "Don't Worry, Be Happy"

The woman who drove the school bus when I was in middle school was named Sue.  Sue had a bit of a lead foot, frequently shouted at other drivers, and had a penchant for wearing dark sunglasses.  Each Friday during the fall of 1988, Sue would also play the cassette single of Bobby McFerrin's "Don't Worry, Be Happy" over and over and over.  She said that it helped to calm her.
