1989 is the upcoming fifth studio album by American singer-songwriter Taylor Swift, scheduled to be released on October 27, 2014 by Big Machine Records. Swift began planning her follow-up project in 2013 and continued work into 2014, during which time Swift collaborated with producers including Max Martin and Shellback. Their efforts resulted in her "first documented, official pop album", which represents a musical departure from the country pop styles in her earlier work. The album's title is the year Swift was born.

"Shake It Off" was serviced as the lead single from 1989 on August 18, 2014. It debuted at number one on the U.S. Billboard Hot 100, becoming Swift's second number-one single in the country and the twenty-second track to debut in the peak position in Billboard history.
