If we're talking the most universally forgettable song, yeah, it's probably "Crack A Bottle".

Personally, though, the only one I'm struggling to remember is "Down".

Definitely Crack a Bottle, probably followed by 3 (although it's one of my absolute favorite Britney songs )

Crack A Bottle whatever that is, it's the only one I can't remember

[Inner Insanity]

I can't believe people saying Down.

Baby are you down, down, down, down, down
Dooowwwwwnnnn
Dooooowwwwwnnn
Even if the sky is falling down

Haven't heard it since probably 2009 and still remember the chorus. It was seriously on every radio station all the time.

Crack a Bottle, followed by 3.

The only two songs I don't remember are "Crack A Bottle" and "Whatcha Say." I voted for the latter though.
