CORTIS (Martin, James, Joohoon, Seonghyun, Gunho) was selected for Billboard's '21 Under 21' list, which recognizes 21 artists/groups under 21 years old, announced on July 31 on Billboard's official website. CORTIS is the only K-pop boy group included in this year's list. The group demonstrated impressive chart performance, with their debut album 'COLOR OUTSIDE THE LINES' reaching No. 15 on the Billboard 200 last year, and their mini-album 'GREENGREEN' released in May of this year debuting at No. 3 on the same chart. Billboard's annual '21 Under 21' selection evaluates artists based on quantitative metrics including album and song sales, streaming numbers, social media exposure, and radio/TV reach, as well as their industry impact and growth trajectory. In addition, the global girl group KATZZ was selected for the second consecutive year, with Billboard praising them for performing at major international festivals and receiving two Grammy Award nominations, marking their most successful year since debut.
