Honestly, I really like this one. I've done a lot of thinking as to the Max Martin style (ex-poodle rocker Max is Britney's songwriter and is basically responsible for the pop zeitgeist - he also does 5ive, NSYNC, Backstreet, even Bon Jovi these days), and believe you me, there is a pretty cynical formula here - verse, bridge, chorus, completely different verse, identical bridge and chorus, breakdown, then chorus to finish. Often this is pretty bad - NSYNC's its gonna be me is the nadir - but in this one it works really well - the verses are slinky, the chorus a classic pop one and basically the whole idea of oops! is pretty funny. I can't pretend I listen to it that often but I enjoy it when I do.
