Out rank her in terms of what?
No one cares about the grammys' or whats on the Billboard charts in the US anymore.
Just because Christina hasn't been around for a few years, it doesn't mean that she isn't capable of creating music that can get more air and club play than Beyonce, Rihanna, Britney and Lady Gaga.

I believe in Christina.
If this album DOES flop after the summer's done, then the haters can start talking.
Until then, there's nothing to criticize, thus why people have to pull up records and speculations from years back to actually have relevance in an argument.
