Can't be the only one to not mind the Fergie anthem... I mean in the context of it all it's not like it's your jazz solo but by no means should she get hate for that ("way-ay-ayve" aside)
It's all well and good to try and improve upon those who have sung something before you, but if you $&!# the bed on a classic (like a National Anthem) you can expect some backlash.
