Sticker (song)
"Sticker" was composed by Dem Jointz, Calixthe, Prince Chapelle, Ryan S. Jhun, Yoo Young-jin, while production was handled by Lee Soo-man. Dem Jointz had also co-produced NCT 127's previous singles "Cherry Bomb," "Kick It," and "Punch." The song features a prominent flute sound and a "minimal" and "subdued" production. The group found the song surprising and difficult to master. Member and co-lyricist Taeyong noted in a behind-the-scenes video that he felt that he was "being punished" and "rebuked" for a song for the first time due to its difficulty in pulling off the song. Member and vocalist Doyoung shared it was their first time where they "dived deep" with Yoo Young-jin while recording the song, with Yoo encouraging the group's rappers Taeyong and Mark to write the song's rap lyrics to "bring out the NCT vibe" with the group in mind. In an interview on "The Travis Mills Show", member Johnny said listeners can expect to be surprised with the flute melody, while Mark described it as a song that "has a lot of impact and a lot of dynamics" that they have "never touched before." Dem Jointz attributed the song's odd structure to “just being different. You want to stand out, but at the end of the day, you still want everybody to get what you’re doing." He also added that the flute sound "makes you get down and boogie." He ultimately called it one of his favorite tracks, saying that he "feels as strong about this record as I do [for] 'Kick It.'"
