"Celebration" is a song recorded by American singer and songwriter Madonna for her third greatest hits album of the same name (2009). It was written and produced by Madonna, Paul Oakenfold and Ian Green, with additional writing from Ciaran Gribbin. The song was released digitally on July 31, 2009, by Warner Bros. Records. Madonna collaborated with Oakenfold to develop a number of songs. Amongst all the songs developed by them, two were chosen for the greatest hits album with "Celebration" being released as the first single from it. It is a dance-oriented song with influences of Madonna's singles from the 1980s and 1990s, and consisting of a speak-sing format bridge. The lyrics of the song invite one to come and join a party.
