Both of these artists were absent for four years and barley released anything in between or appeared anywhere. Christina tried to comeback but sadly she failed miserably.
But what about Avril? WTH peaked at #2 in iTunes and currently it's falling rapidly. The radio updates are so-far slow, but that doesn't mean anything.
So on the long run, will What the Hell be more successful than Not Myself Tonight, US and Worldwide?
I think it's going to be a hit! Avril just needs to promote!
