On any given day, I cycle through at least a couple of moods. Each of these moods has one or more corresponding songs. For instance, when I'm feeling particularly proud of myself about a headline or, say, a really good grade on a test, I hear "Stayin' Alive" or "We Are the Champions." When I'm feeling sorry for myself, it's "Nobody Knows the Trouble I've Seen" or the "I'm Gonna Eat Some Worms" song. Today, I'm wild with disco fever.
