Taylor Swift is saying goodbye to country music, for now: The singer says she's releasing her first full-length pop album on Oct. 27.
The 24-year-old revealed in a livestream via Yahoo! on Monday that "1989," named for her birth year, is her "first documented official pop album."
The first single is the upbeat jam "Shake It Off," which she debuted during the livestream and was released Monday. She danced happily in a cropped white top and skirt with the audience as the song played.

Swift called her upcoming fifth album a "rebirth."
"We made the most sonically cohesive album I've ever made," she said of "1989," which was available for pre-order on Monday.
Swift's last effort was 2012's "Red," which sold 1.2 million copies in its first week. Swift said she was mainly inspired by late '80s pop music when recording "1989" over the past two years.
"I woke up every day ... not wanting, but needing to make a new style of music than I made before," she told the audience.
The singer also premiered the music video for "Shake It Off" during the livestream. The song was produced by Max Martin and Shellbeck, who helmed the Swift hits "We Are Never Ever Getting Back Together" and "I Knew You Were Trouble."
