Known primarily as a country artist throughout her career to date, Swift made a deliberate choice to showcase her pop side on 1989, her fifth studio album, which she announced this past August. 1989 hits stores and digital outlets on Monday, Oct. 27.

"This is my very first documented, official pop album," said Swift. At the same time, she also emphasized that it's "the most sonically cohesive album I have ever made and my favorite album I have ever made."

The title 1989 has significance not only because it's the year of Swift's birth, but because that decade was part of her musical inspiration this time around. "I spent two years making 1989," explained Swift. "Two years gives you enough time to grow and change and let things inspire you. I was listening to a lot of late '80s pop music and how bold those songs were and how that time period was a time of limitless possibilities. In thinking about that, this album is a rebirth for me."

Swift has released three advance tracks from 1989: "Shake It Off," "Out of the Woods" and "Welcome to New York," as well as a snippet of a song called "Style" that's included in a Target ad.

"Shake It Off" was the album's official lead single. It dropped in August and immediately earned widespread attention and airplay. Pretty much the entire premise of "Shake It Off" is dancing. And in the video for the song, Swift does so with all kinds of folks and in what seems like a million different dresses. There's the ballerina getup, the cheerleader, the Gaga-esque futuristic shot, the hip-hop video - you name it, Swift dances it.
