The British actor and musician features at the beginning of the video, dressed ostentatiously in a black and white fur coat and Homburg hat.

And The Jungle Book star, who is listed as a featured artist on Dance Off, delivers its opening lines, "I challenge you to a dance off/Hands off, no trash talk, no back walk/On the black top, just me, you, that's all/No cat calls, no tag teams, no mascots."

Thanks to the cinematic promotional clip, directed by Ryan and Jason Koenig and released late on Tuesday (17May16), the song quickly rose to the top of America's Billboard Trending 140 chart, which lists the songs shared the most on Twitter over the past hour.

Dance Off, for which Idris has a writing credit, first appeared on Macklemore & Ryan Lewis's second album together This Unruly Mess I've Made, released in February (16).

MACklemore, who has worked with his friend Ryan, a DJ, since 2006, was so delighted with the song's rise to the top of the trending chart that he shared a photo of its number one status on Instagram.

As well as his impressive acting career, Idris has long had a sideline as a DJ and musician. He has appeared on albums by Pharoahe Monch and Jay Z, and opened as a DJ for Madonna on the Berlin leg of her Rebel Heart world tour last year (15).

Last month (Apr16), British dance legend Norman Cook revealed that he had teamed up with the 43-year-old to record a track, which is as yet unreleased.
