Based on a 2015 end-of-the-year music report by Nielson Music, “Uptown Funk” raked in sales of approximately $5.5 million in the United States. James’ contribution earned him 8 percent of the popular funk song, as reported by Billboard.

While James is one of the most famous artists receiving co-writing credit on the song, “Uptown Funk” has eleven total writers listed as contributors (which did not start out that way).

Other writers outside James, Ronson, and Mars include Jeffrey Bhasker, Philip Lawrence, Devon Gallaspy, and the five associated members of The Gap Band. The latter group was added after a court claim of similarity of their 1979 song, “Oops Upside Your Head.” This would mean that all eleven credited contributors have to split song revenue, according to the terms of their respective publishing deals.

“The original songwriters agreed to share credit with the Gap Band’s members — Charlie, Ronnie, and the late Robert Wilson, as well as keyboardist Rudolph Taylor and producer Lonnie Simmons — for a share of 17 percent. With those names now added to the song, they have to once again split the difference, with the original four writers’ shares dipping down to 17 percent. (Trinidad and Gallaspy’s shares remain unchanged.),” Vulture explained in May 2015.
