I would have loved Britney to record this. It's a non-melody mess, but it's a rare case where that works in the song's favor, I think primarily because it's a fantastic booty jam and it's not really necessary for any interesting melodies to be developed. But I also have to consider the fact that if Britney taken the song it would have (most likely) been rewritten in certain parts to better fit her persona. In doing so I think they would have killed some of that bad ass attitude the song has.
