Uptown Funk is a funk-pop, soul, boogie, disco-pop, Minneapolis sound track, with a light EDM influence song by British record producer Mark Ronson featuring American singer and songwriter Bruno Mars. It was released on November 10, 2014, as the lead single from Ronson's fourth studio album, Uptown Special (2015).

The song began to be written during a freestyle studio session while they worked on a jam Mars and his band had been playing on tour. Copyright controversies arose after the song's release resulting in multiple lawsuits and amendments to its songwriting credits.

In its seventh week, "Uptown Funk" topped the Billboard Hot 100, with 382,000 downloads sold, 10 million U.S. streams and a 76 million airplay audience. The song is Ronson's only number-one single in the country and Mars's sixth. It became one of the longest running number-one singles on the Billboard Hot 100 and the third longest-running number-one single of the 2010s decade topping the chart for 14 consecutive weeks until it was replaced by Wiz Khalifa's "See You Again" featuring Charlie Puth. It topped not only the Billboard Hot 100-year-end chart, but also the Decade End Billboard Hot 100.

The song received generally favorable reviews from music critics, who praised its catchy melody, danceable beat, and Bruno Mars's vocals. The song was also nominated for two Grammy Awards, including Record of the Year and Song of the Year.

Here are some of the reasons why Uptown Funk is such a popular song:
