Neither OPRAH nor the Grammy's arethe arbiter of "cool", let us not forget that....unless you are a middle-aged, middle-class white woman. OPRAH's endorsement is a BUSINESS move, nothing else....
I like the song but Beyonce has got to come harder in performance to be groundbreaking. Madonna has done that, Janet has done that, Britney has done that. Not mad at her and still looking forward to her record because GaGa and Britney's music is garbage now.

Perhaps she put something together to fulfill the obligation but not overshadow the video....I will be watching.
