Kind of, but I don't really see it as a diss to Taylor seeing how it's not her fault or anything. Regardless of how "pop" people say she is now, she's still country enough to lose a lot of worldwide appeal. She's doing pretty damn good in regards to worldwide sales all things considering.
And I bet other stans wish their faves could be as "local" as Taylor is. The girl is selling as much, if not more, in the US than their faves are worldwide. Case closed.
