Goodness, I'm no stan of hers, but you all need to let Taylor do Taylor. She knows what she wants to do with her direction.
What would've happened if Britney had never ventured out from bubblegum pop and released "I'm A Slave 4 U"? We wouldn't have any of her discography past her first two albums.
And what if Katy hadn't left her pop/rock roots? She wouldn't be tied with the king of pop for most number 1's from an album.
And if Rihanna hadn't transitioned from Caribbean dancehall when she released "Umbrella"? I don't think she wouldve gone far releasing repeats of "SOS" and "Pon de Replay".
And what if Shakira hadnt started making English music? Well "Hips Don't Lie" wouldn't be the biggest selling single of the 2000's.
There are many more examples, but you all get the point. Taylor knows what she's doing, so don't doubt her like this. Personally, I'm here for a new sound.
Katy, Shakira, Rihanna and Britney are all mainstream pop artists. They don't cater to a niche. They have to change their styles to stay relevant.
She's doing one of two things:
1) Creating her Can't Be Tamed album and alienating her country fans, or
2) Following in the footsteps of Shania Twain and releasing two versions of Red pleasing both pop and country fans.
