"Shake It Off" is a song by American singer-songwriter Taylor Swift. It was written by Swift and its producers, Max Martin and Shellback. "Shake It Off" is an uptempo dance-pop song featuring a saxophone line in its production. The lyrics are about Swift's indifference to her detractors and their negative view of her image. The song was the lead single from her fifth studio album, 1989, which Swift marketed as her first pop album. It was released for digital download worldwide on August 19, 2014, by Big Machine Records.
Contemporary critics found the song's dance-pop production catchy, but some believed the lyrics were weak. Retrospectively, critics have considered "Shake It Off" an effective opener for the 1989 era, which transformed Swift's sound and image from country to pop. The song featured on 2010s decade-end lists by NME and Consequence of Sound. In the U.S., the single spent 50 weeks–including four weeks at number one–on the Billboard Hot 100, and received a Diamond certification from the Recording Industry Association of America (RIAA). "Shake It Off" also topped charts in Australia, Canada, Hungary, New Zealand and Poland.
The single was supported by a music video directed by Mark Romanek. The video, in which Swift portrays a clumsy person attempting to practice several dance moves without success, attracted accusations of cultural appropriation for featuring dance routines associated with people of color such as twerking. To promote the song, Swift performed on televised live events including the MTV Video Music Awards and the iHeartRadio Music Festival. She included "Shake It Off" on the set lists for two of her world tours, the 1989 World Tour (2015) and Reputation Stadium Tour (2018). The song has received numerous accolades, including Favorite Song at the 2015 People's Choice Awards and three Grammy nominations at the 2015 Grammy Awards.
"If I Could Turn Back Time" is a song recorded by American singer and actress Cher for her nineteenth studio album Heart of Stone (1989). It was released on July 1, 1989, by Geffen Records as the album's lead single. The song was written especially for Cher by Diane Warren, who produced it with Guy Roche. Cher initially disliked the track after listening to a demo tape sung by Warren, but subsequently changed her opinion after Warren convinced her to record it.
Highly successful around the globe, "If I Could Turn Back Time" was seen as a major comeback for Cher in the late 1980s. It charted at number one in Australia and Norway, as well as reaching number three in the United States and number six in the United Kingdom. It also became Cher's second consecutive solo number-one hit on Billboard's Adult Contemporary chart. The track was certified Gold by the Recording Industry Association of America (RIAA) for the sales of 500,000 copies. In November 2011, Billboard reported the digital sales of "If I Could Turn Back Time" to be 394,000 in the US.
