EXO's electro-pop tour de force THE WAR keeps the goodies coming with a supplemental EP of even wider-ranging tracks. The band's most cheery single in years, "Power," is an anthem whose chorus just begs to be chanted in an arena. "Boomerang" explores the outfit's mostly untapped funk-pop potential, while "Sweet Lies" returns EXO to the sensuality of 2012's "What Is Love," with some smoky trap production and sophisticated lyrics by rapper Chanyeol and R&B star G.Soul.
