I've read that play plots are man vs man, man vs self etc. I've never thought about the "plots" for songs or even jokes. Thanks for this insight! It's like how you overcome the superego and celebrate the id. That line, "it's great to stay up late" always disturbed me, truthfully. They seemed naughty for saying it, or it seemed too daring for the innocent tone of the song. Now I understand why. My own little superego was being lit up!
