perfection.

It's still "Womanizer."

The one who's album far outsold the other.

The one that won 3 Grammys.

The one that is iconic, and NO they're not both iconic.

The one with actual vocal delivery.

The one who's recording artist can freakin perform WELL and sing PERIOD, let alone amazingly.

The one who's music video is the most viewed of all time.

I'll stop.

Single Ladies.

I like Single Ladies. A lot. But you have no idea how much I LOVE Womanizer.

Single Ladies is my least fave single from Beyonce.
and Womanizer was pop perfection.

I love "Womanizer" but "Single Ladies">>>>>>>>>>>>>>>>

I'm going to vote for "Single Lad---I'm sorry, Kanye, I'mma let you finish, but "Single Ladies" is one of the most annoying songs of all time! Of all time!

It didn't work out like you'd have hoped.

I would go as far as to say that Womanizer is very possibly one of the best Britney singles.
