MAX’s first taste of pop superstardom was extra sweet: He wrote “Lights Down Low,” a 2016 collaboration with bummer-rap sensation gnash, as a way to propose to his then-girlfriend. The onetime child star turned to pop in the mid-2010s, showing himself to be a versatile vocalist on tracks like the buoyant “10 Victoria’s Secret Models” and the wobbly Lil Uzi Vert collab “Wrong.” In 2020, he celebrated his recovery from vocal-cord surgery with songs that showcase his lifelong appreciation for hooky, romantic pop, like the wistful Hayley Kiyoko duet “Missed Calls” and the love-happy SUGA collab “Blueberry Eyes.”
