DESCRIPTION:
Mercy is a song performed by British singer Duffy, released as the second single from her debut album, Rockferry. Co-written by Duffy and Steve Booker and produced by Booker, it was released worldwide in 2008 to critical acclaim and unprecedented chart success.

Mercy was nominated for several awards in 2008, including the Grammy Award for Best Female Pop Vocal Performance at the 51st Grammy Awards. Well received by the public, Mercy went on to become the third-best-selling single of 2008 in the United Kingdom, with sales of over 500,000 copies in the UK that year. The song achieved worldwide chart success, with Duffy attributing this to the fact that "everyone is searching for liberty, from themselves or from the world they've created around them" and "everyone would like to be set free". It is Duffy's best-selling single to date.

Dancing Queen, a remake of British singer Duffy's song, Mercy, is the first Korean material released by the group after a 14-month hiatus from Korea in which time the group released a series of Japanese singles and their second full-length Japanese studio album, Girls & Peace. The single was released digitally on December 21, 2012 on the same day as the music video. Back as of the released of Girls' Generation's big single Gee, Dancing Queen was originally going to be released instead of Gee, but due to "unkown reasons", Dancing Queen was pushed back and later released.

Girls' Generation - Dancing Queen PLAYED IN LEFT EARPHONE.

*NOTE* On some mobile devices such as iPhones, the video might play both songs in both earphones, but on a laptop/computer the video seems to play the songs on the left and right earphones as it should be. *NOTE*
