K-pop girl group TWICE are back with two brand-new Japanese songs on Tuesday (June 11).
“Happy Happy” and “Breakthrough” are a pair of mirror tracks, with the first meant to represent the brightness of a summer day and the latter meant to evoke the feelings of a cool summer night. Fittingly, “Happy Happy” is a bouncy dance track similar to many of TWICE’s past songs, with its euphoric choral repetition of the titular phrase and a clapping beat guiding much of the melody, while “Breakthrough” offers up a dramatic, brassier electro-pop sound that puts the nonet's silky smooth vocals front and center. The latter comes off like a sequel to the act’s most recent Korean single “Fancy,” which similarly shifted the focus to TWICE's maturing sonic style.
