Because if so, then Gaga had a huge head start with her song coming out in Feb while Rihanna's came out in september. We Found Love was still doing strongly going into 2012

The ifpi source is for BTW. I dont remember seein WFL in there.

I know that its closer now but BTW still sold more than WFL.
