Jack Avery, Corbyn Besson, Jonah Marais, Daniel Seavey, and Zach Herron were stars in their own right before coming together to form Why Don’t We—but as a unit, these five guys are a pop force, offering a next-generation take on the boy-band ideal. Their sweet harmonies and synchronized charm carry serious songs like the introspective piano ballad “8 Letters” as effortlessly as they do slinky electro-pop tracks like “Something Different,” while their social-media-honed senses of humor shine through, too, with tracks like the sardonic Macklemore collab “I Don’t Belong In This Club” taking aim at sacred cows of cool.
