NEW YORK (AP) _ 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 after 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.
Swift said her upcoming fifth album, which was mainly inspired by late `80s pop music, is the ``most sonically cohesive album I've ever made.''
``1989'' was available for pre-order Monday. The singer also premiered the music video for ``Shake It Off'' during the livestream.
Swift's last effort was 2012's ``Red,'' which sold 1.2 million copies in its first week.
