If you have the power to save one song from them... you have the power to save them all. Destroy glee, then they cannot harm any other songs.
Ehh, its a moot point, because Glee only really works poppy type songs, which aren't that big of a loss anyway.
EDIT: One thing I did resent on the one episode I did watch of it. (the madonna ep) in the early part of the Ep, one char asks "what do you think of when you hear the name madonna?" and the supposedly "macho" guy says "Legendary MILF" Uh, no, No straight guy in his right mind within the last 25 years has seen Madonna as anything resembling attractive.
When I heard it I thought this the second gayest thing Ive ever heard right behind "Im shooting a back door pilot for Bravo"
