And yet it turns out that the same handful of top writers and producers are behind hit after hit—a mysterious priesthood of musical mages. They combine the talents of storied arrangers like Quincy Jones and George Martin, with the tune-making abilities of writer-producers like Holland–Dozier–Holland, Motown’s secret weapon. On the pop side, there’s Ryan Tedder, Jeff Bhasker, and Benny Blanco; on the urban side Pharrell Williams, Dr. Dre, and Timbaland. Bridging both genres are the über hit makers like Stargate, Ester Dean, Dr. Luke, and Max Martin.
