Taylor Swift named her fifth album after her birth year, 1989, but 2014 is the year of her rebirth. After wooing the mainstream with four albums of her pop-flavored brand of country, Swift waves goodbye to Nashville with 1989, ditching guitars for new wave-y synths, courtesy of hitmakers who include Max Martin, Shellback, Ryan Tedder and fun.’s Jack Antonoff, whom she met through his girlfriend and her “best friend” Lena Dunham.

But the LP also marks a personal transition for the 24-year-old: She has a new cropped haircut, debuted a more sophisticated street style and, perhaps most symbolically, moved from Nashville to New York in March. In the past, Swift often seemed to use her music to call out a string of ex-boyfriends. Some already have pointed to One Direction’s Harry Styles as the inspiration for new single “Out of the Woods.” She is, however, currently single — “in the past two years, [boyfriends] have not been a priority,” she says.

Swift’s mature metamorphosis is going swimmingly so far: “Shake It Off” debuted at No. 1 on the Billboard Hot 100, the album is arguably the best of her career, and industry forecasters expect it to sell 800,000 to 900,000 first-week copies — the best sales week for an album in 2014. As 1989 arrives Oct. 27 on Big Machine Records, Swift reveals the reasons behind her professional and personal transformations. “I’ve gone through so many phases, and I’ve had to learn so much in front of the entire world,” she says. “I feel much more equipped to deal with things now.”

I like to look at albums as being sort of statements. Visually, sonically, emotionally, I like them all to have their own fingerprint. This time I’m kind of just doing whatever I feel like. I felt like making a pop album, so I did. I felt like being very honest and unapologetic about it, so I was. I felt like moving to New York — I had no reason to; it wasn’t for love or business — so I did. I felt like cutting my hair short, so I did that too. All these things are in keeping with living my life on my own terms. That’s what I’ve been celebrating about this phase in my life because it has made me really, really happy.

“Shake It Off” is about how I deal with criticism and gossip and humiliation and all those things that used to level me. Now I deal with those things by laughing at them. I didn’t want it to feel victimized. Four years ago, I put out a song called “Mean” from the perspective of “Why are you picking on me? Why can I never do anything right in your eyes?” It was coming from a semi-defeated place. Fast-forward a few years and “Shake It Off” is like, “You know what? If you’re upset and irritated that I’m just being myself, I’m going to be myself more, and I’m having more fun than you, so it doesn’t matter.”

Relocating to Manhattan seemed to be really key for you — you start 1989 off with “Welcome to New York.” That song is about the kind of wide-eyed optimism with which I approached my move to New York. I was so excited by the idea of embarking on a new adventure, and the way that song sounds is basically mirroring that emotion, like, “Anything’s possible here.
