Katseye is the six-member global girl group formed through HYBE and Geffen Records' Dream Academy, and 'Debut' was the title track introducing them to the world in 2024. The bright, confident pop sound quickly became a shorthand for the group's arrival, shared by fans known as Eyekons in performance clips, dance covers and introduction edits across TikTok and YouTube. Because the track marks a beginning rather than a single moment, creators still reach for it whenever they want a fresh, upbeat opening that signals something new is starting.
