The second of Big Bang’s six title tracks off Alive, “Bad Boy” crawls the streets of Brooklyn as the members of Big Bang apologize for being less-than-stellar boyfriends. With G-Dragon and TOP’s rhythmic rapping flowing right into the chorus, brought to life by Taeyang’s smooth vocals, the track flickers back to a soulful R&B sound that we haven’t heard too much of since the group’s rookie days — a real treat for early VIPs who miss Big Bang circa “Forever with You.”
