CORTIS’ ‘GREENGREEN’ EP: Ranking All 6 Tracks From the BIGHIT MUSIC Group
BIGHIT MUSIC group CORTIS ranks all six tracks from their second EP, "GREENGREEN," showcasing their refined sound through studio routines, restless instinct, and self-definition.

CORTIS ‘ second EP, GREENGREEN , treats identity less as a fixed statement than as material to test and push into shape.
The six-track project arrived May 4, nine months after the five-member BIGHIT MUSIC act debuted with COLOR OUTSIDE THE LINES , which entered the Billboard 200 at No. 15. Made up of MARTIN, JAMES, JUHOON, SEONGHYEON and KEONHO, CORTIS has since built on that opening through multiple rookie awards, a headlining slot on the opening night of the NBA Crossover Concert Series at NBA All-Star 2026 and an upcoming Lollapalooza appearance in August as the only K-pop boy group on the lineup.

That trajectory gives GREENGREEN a clear external narrative. The more revealing story is internal. Across the EP, the members’ writing credits turn their “young creator crew” framing into something more concrete. MARTIN appears as a writer on all six tracks, while all five members share writing credits on “REDRED,” “ACAI,” “YOUNGCREATORCREW” and “Wassup.” His role also extends behind the board, with recording engineer credits at the group’s MARS studio across the project and producer credits on “ACAI,” “YOUNGCREATORCREW” and “Blue Lips.” SEONGHYEON joins the production and synth credits on “ACAI.”
Rather than read as a slogan, that authorship becomes a method: Studio routines, everyday references, youthful bravado and quieter moments of reflection become the raw material of a sound the group is still finding.
The result is less a manifesto than a working portrait. “REDRED” gives the EP its clearest center, translating the group’s green-versus-red logic into sound, language and movement. “TNT” turns live-wire rookie energy into a distinct opening jolt. “YOUNGCREATORCREW” plays knowingly with the language already attached to the group, while “Wassup” and “Blue Lips” drop into quieter, more personal registers. Even where the EP is still testing its edges, its strongest moments suggest a group beginning to recognize what only it can say.
