Pop is what she's best at. She can add in some slower and more personal tracks and whatnot but pop has to remain the core of ha music. If not, then whatever she does better be good or I'll have to demote myself from stan to fan.
Is there really an artist who did the same type of music during his/her whole carreer?
I think you just need to experiment with different genre's to keep it fresh for yourself but also your fans.
