“All Night” is a song recorded by South Korean girl group Girls’ Generation for their sixth studio album Holiday Night (2017). The song was released digitally on August 4, 2017 as the album’s single alongside “Holiday” by S.M. Entertainment.
According to Billboard’s Tamar Herman, “All Night” is a nu-disco tune in the style of a bubblegum pop song that features a 1980s vibe with “thumping” bass and “twinky electronic” melody. Jacques Peterson from Idolator described the track as “funky nu-disco” that turns “a teenage slumber party into Studio 54.” Lyrically, the song is a dedication to Girls’ Generation’s longevity and bond with their supporters which, according to Herman, is “atypical” for K-pop girl groups.
All Night” debuted at number 35 on the Gaon Digital Chart, on the chart issue dated July 30 – August 5, 2017, with 47,802 downloads sold.
