For going on five years now, the record producer Mark Ronson says he has been known by no small number of casual music fans, if they can identify him at all, as “the white guy from the Bruno Mars video.”

The fact that “Uptown Funk,” one of the most successful and recognizable pop smashes of this century — with 3.5 billion views on YouTube, 14 weeks at No. 1 and a Grammy for record of the year — actually appeared under Ronson’s name on his 2015 album, “Uptown Special,” is but a trivia footnote. And he’s fine with that.

Because for most of his career, Ronson — the princely heir to a New York-via- London society-page family turned downtown D.J. turned super-producer — was the type to feel most comfortable in the studio and in the liner notes for modern giants like Amy Winehouse, Adele, Lady Gaga and Mars. (His parents are Laurence Ronson, a real estate entrepreneur, and Ann Dexter-Jones, the socialite who went on to marry Mick Jones of Foreigner.)

But the problem with succeeding so consistently — and with being leading-man handsome, with a head of hair that actual leading men might pay thousands for in Beverly Hills — is that eventually people start to get curious about you , especially amid the rise of D.J.s and producers as pop stars, including Diplo, Calvin Harris and the Chainsmokers.
