K-pop’s teen rebels CORTIS add two songs to the tracklist of GREENGREEN for this extended version of their 2026 EP. Here, the turbulent energy of smash hit “REDRED” and the brainrot-styled bassline of “ACAI” are joined by the self-referential swagger of “PACK IT UP” and the overflowing aspiration of “MONEYMONEYMONEY.” As with the returning tracks on the EP, the young members of CORTIS played a behind-the-scenes role in shaping both songs, a vital function of the K-pop crew’s identity that James, Juhoon, Martin, Seonghyeon, and Keonho explain on “YOUNGCREATORCREW,” lending an earnestness to their lyrics. When Keonho raps, “Even after living like a hippo for half a year, I’m still hungry/I want to stand in the sports complex and hear that’s so fire” on the anthem manifesto, he means it.
