Dancing Queen by Girls’ Generation

"Dancing Queen" is a Korean song by South Korean girl group Girls' Generation. It was released on December 21, 2012 as the lead single from their fourth Korean studio album, I Got a Boy (2013). Recorded in 2008, the song was initially scheduled to be released as the title track for the group's first extended play. Nevertheless, the plan was withdrawn, and "Gee" and the titular EP was released instead."Dancing Queen" is a remake of the 2008 single "Mercy" by Duffy. It is the first Korean material released by the group after a fourteen-month hiatus from the South Korean music scene to focus on the Japanese music market with their 2012 album Girls & Peace. The song received generally positive reviews from music critics, who favored its "funky pop" production as opposed to the group's signature electropop styles. Commercially, the single peaked atop the Gaon Digital Chart and at number two on the Korea K-Pop Hot 100, and has sold over 500,000 digital units.
