Has the cast of GLEE gotten a little too full of their own press?

Two bands (Kings of Leon and Foo Fighters) have turned down  requests to use their music during an episode of the award winning show.  The creator of the show, Ryan Murphy, took it upon himself to rage -- and I say that because I seriously can't repeat a word from his awful tirade -- naming names while elevating the supreme status of GLEE.    

Um, not!  Check out this apology.
