CORTIS Joins BTS in 2026's 4 Million-Seller Club

CORTIS has reached another milestone with its second EP, "GREENGREEN," surpassing 500 million cumulative streams on Spotify about five months after its release.

According to Spotify data as of Oct. 12, the six-track album, led by title song "REDRED," has accumulated more than 500.1 million streams.

The EP first crossed 100 million streams just 15 days after its May release, more than twice as fast as the group's debut album, "COLOR OUTSIDE THE LINES," which took 34 days to reach the same mark.

CORTIS has also continued performing internationally, including an appearance at the 2026 Formula 1 Singapore Grand Prix on Oct. 9.

Following the performance, "REDRED" climbed to No. 26 on Spotify's Daily Top Songs Singapore chart before rising to No. 22 the next day. Earlier tracks including "GO!," "FaSHioN" and "JoyRide" also reentered the chart.

The album has performed strongly in physical sales as well, surpassing 4.35 million copies on Circle Chart. Including its expanded edition, "GREENGREEN_playextended," total sales are approaching 4.5 million.

CORTIS and BTS are the only K-POP acts to have released albums selling more than 4 million copies in South Korea this year.
