Uptown Funk

This is not a Bruno Mars album track: it is Mark Ronson's "Uptown Funk (feat. Bruno Mars)", lead single of Ronson's Uptown Special (2015). Ronson, Mars, Lawrence and Jeff Bhasker wrote it, and Ronson, Bhasker and Mars produced; additional credits went to Trinidad James and Devon Gallaspy for "All Gold Everything" and, in May 2015, to members of the Gap Band for "Oops Up Side Your Head". It was released on Columbia, Sony and RCA with "Feel Right" as the B-side; the album version runs 4:30, the radio edit 3:55, at 115 bpm in D Dorian. The UK release was moved up to December 8, 2014 after Fleur East performed a cover on The X Factor.

It was recorded across six studios in 2014, among them Royal in Memphis, Zelig in London, Cherry Beach in Toronto, Armoury in Vancouver and Daptone in Brooklyn. Ronson worked on it for about seven months and over 100 takes, starting from a jam Mars and his band played on tour; Mars told Rolling Stone that the solution finally was that they just needed to dance. Serban Ghenea and John Hanes mixed it and Tom Coyne mastered. Hit Songs Deconstructed notes vintage Linn drums, a Korg Trident synth and a 17-second intro. The video, directed by Mars and Cameron Duddy, came out on November 17, 2014 on the New York Street backlot at 20th Century Fox Studios. It spent 14 consecutive weeks at number 1 on the Hot 100 and debuted at number 1 in the UK on December 14, 2014. Sources differ on the number of weeks at UK number 1.
