Most of 'The Club' songs are pretty damn gay these days, clubs have never played Britney because of the massive gay stigma to her name.
I do miss the days of 2007 when that stigma had vanished because she was 'crazy' and it became a bit subversive and 'cool' to like Britney Spears. Every time 'It's Britney Bitch' sounded in a straight club, it'd always get a cheer - there's just something about it.
I remember I heard the Paul Oakenfold remix of Gimme More a lot.
