"Shake It Off" is a song by the American singer-songwriter Taylor Swift and the lead single from her fifth studio album, 1989 (2014). She wrote the song with its producers, Max Martin and Shellback. Inspired by the media scrutiny on Swift's public image, the lyrics are about her indifference to detractors and their negative remarks. An uptempo dance-pop song, "Shake It Off" features a looping drum beat, a saxophone line, and a handclap–based bridge. Big Machine Records released it on August 18, 2014, to promote 1989 as Swift's first pop album after her previous country image and sound.
