Taylor will outsell Britney in the US. She's still has her country fan base. And as long as she's smart to keep them she will pass her.
And Bie you're wrong. The US is not the most important market (there aren't any). But it's still the biggest (Japan is closed off). The UK is second by a large margin, and well Britney has payed that country dust. And we know how the Brits are with their artists so she has to be active with them to sell. Germany is third and she pays then dust too.
Taylor needs around 4 or 5 more consecutive 4x platinum certified albums in the US just to tie Britney in the US, it won't be anytime soon, lets not worried about it now
someone did never mind.
it's one of her best songs.
Like, child, NO.
