I don't think she can go back to Country for the time being. She was big when she was a Country star. But since crossing over, she has exploded because of
1989. Now if I were her manager, I would keep her in the Pop world for the time being. I certainly wouldn't allow her to go back to country if she intends to also do the Pop thing. People would get confused and that translate into fans looking elsewhere. She has to ride the wave and then when she gets it out of her system (if she ever does), then and only then let her go back to where she started. That's my business 101.

To answer your question, she is full-on pop. No country to be found anywhere and for me that is a huge plus.
