Dev Hynes isn’t a super-producer — he’s never had a hit on the Billboard Hot 100 or mainstream radio — but a growing swath of indie-leaning pop and soul music bears his mark. Since he first began recording as Blood Orange in 2009, Hynes’ stylish midtempo balladry and ’80s-indebted R&B have bled into celebrated collaborations with Solange, Sky Ferreira, Florence + the Machine and more. On second solo album “Cupid Deluxe,” he brings new collaborators into the fold while demonstrating an increased focus on songcraft. Lead single “Chamakay,” featuring a show-stopping cameo by Chairlift’s Caroline Polachek, is airy, evocative and dripping with feeling. Meanwhile, the epic “Chosen” melds a choir, a saxophone and a drum-machine loop borrowed from Jimmy Jam and Terry Lewis. The mode here is mostly lush, slick and somber, but there’s enough variety to keep listeners intoxicated.
