Hm. Gets into a sticky area here. Is the song melodically interesting(would it exist without the lyrics?) Is it more meaningful when the singer is known, and is that the same thing as the singer's songs being known? What's the difference between "_______ is a Big Jerk" and "Stardust"?X.J. Kennedy once published an anthology of poetry withough biographical details about the writers, or even their names, to see if the things would stand on their own. Or do we love the illusion of these singers as friends?
