Coldplay disdains everything about American football. It’s sort of amusing that they’d deign to play halftime on the one hand, but irritating on the other because they’ll no doubt get their little digs in.
I don't know anything about them, other than the crappy music of theirs I heard when I checked them out on YouTube.
As for Beyonce, not only is she tremendously overrated, she and her hubby JZ are big supporters of Fidel Castro. Well at least they don't have HER or him doing the National Anthem!
