One of K-pop’s premier boy bands, BOYNEXTDOOR set out their stall with their name, one that suggests an easy-going affability. That translates to their music too: Expect hooky refrains, infectious melodies, and a sense of irrepressible optimism from the six-piece. Their range encompasses upbeat pop (“123-78,” “I Feel Good”), emotive love songs (“IF I SAY, I LOVE YOU,” “Never Loved This Way Before”), and moments of blissed-out reflection (“So let’s go see the stars”). The natural looseness with which they blend synth-pop, rock, hip-hop, and R&B imbues BOYNEXTDOOR with a real sense of authenticity.
