ABCD has the driving force of a Crazy In Love. Or, to put it in K-pop terms, it sounds like something Ailee might have unleashed during the first few years of her career. Nayeon clearly enjoys this sound and revels in ABCD‘s breathless blend of bombast and swagger. It’s a stitched together string of highlights, from the charismatic hip-hop of the central drop to the explosive brass that follows. Not every moment is equally engaging, but there’s always a peak waiting around the corner. Nayeon ties it all together with plenty of attitude, wrapping her vocals around a variety of rhythms and tones.
