Global superstars Lady Gaga and Jennifer Lopez released the lead singles to their albums during February of 2011. Both turned out to be huge hits - selling over 8 million copies WW in that year alone.
Which song was the bigger hit on a worldwide scale?
On The Floor was like the biggest song of 2011.
I'm kinda biased though cause it was basically made for Europe so it was probably much bigger here than it was in the US.
