There are countless numbers of people who none of us want to hear cover Linkin Park on YouTube but they do it anyway. I don't think anything is off limits to the Glee folks; if you find out they're covering LP and expect a note for note rendition then you fail to understand how good covers are done: by putting a new twist on the song(s) in question.
I think Finn would be a great Chester and Puck would be a great Mike. I would love to see a cover of Points of Authority.
probably something like leave out all the rest..the messenger..and would just further the ignorant public to think linkin park has "sold out" and are a bunch of little girls
^ This. For some reason Bleed It Out just keeps popping into my head, not that it'd fit in one of the episodes.
