“Uptown Funk” spent 14 weeks at No. 1 on the Billboard Hot 100 for Mark Ronson and Bruno Mars.
Released in late 2014, the song was credited to British producer Mark Ronson featuring American singer Bruno Mars. Its sound draws on funk, soul, boogie, and Minneapolis-style pop, with a prominent horn arrangement and rhythmic vocal delivery.
The single first reached No. 1 in January 2015 and remained there for 14 nonconsecutive weeks. It became one of the defining pop hits of the 2010s and earned major awards, including the Grammy Award for Record of the Year.
The credit can cause confusion because many listeners casually call it a Bruno Mars song. Officially, however, it is a Mark Ronson single featuring Mars. The two artists also co-wrote it with Jeff Bhasker, Philip Lawrence, Devon Gallaspy, and others.
