I thought that pre-order didn't count sales till it's released
You're right. Sunday is the release day for singles. Avril is under a different Sony extension label in the UK I believe. So I guess they decided to release it today. Smart move if she is on The Voice this Saturday Though next Sunday would have been better
Radio with positive update i Tought it was over!!! Maybe this is the last chance for this single at radio!! + promo comming this thursday and sunday the MuchMusic Video Awards
+ she is doing great at iTunes it would be at least 1million in 1 or 2 months
