Prior to the crash, Ladies' Code's music had been predominantly pop with a retro sound. Billboard magazine noted that the group blends in "modern electro-pop" with "classic throwback elements" and powerful vocals. The group's debut single "Bad Girl" was described as a swing/jazz-inspired track accompanied with solid vocals. Their follow-up single, "Hate You" was marked as a departure, returning with a mid-tempo dance song with a combination of brass and acoustic guitar arrangements.
