Composition
“Icy” was written by J. Y. Park and Penomeco. The song is written in the key D major and has a tempo of 125 beats per minute. It has been described as a “fiery and energetic summer song that promotes the quintet’s passions about music. In a showcase, Itzy described the song as an extension of the group’s first record, "Dalla Dalla,” sharing similar meanings but having a more festive and upbeat air. The pre-chorus lyrics, consisting of lines such as “Icy but I’m on fire” and “Look at me, I’m not a liar,” serves as the lead-up to the dynamic chorus of the song, and according to Billboard’s Tamar Herman, “may as well be the girl group’s anthem.
