Writing new one-note songs

MEGA-TUNE: Motherlover.
KURT: Und dat's the Mega-Tune version of "Ave Maria".
BART: The great thing about Mega-Tune is once consumers are trained to like it, we can stop using existing stuff and just create new one-note songs.
BART: Kurt, sing him the gem you wrote this morning.
KURT: I mean, you know, I'm still playing vit it.
JOEL: Haunting.
BART: Ooo. I like that. Did you just write that, Joel?
