SEOUL, Sept. 24 (Yonhap) -- "Butter," a megahit single by K-pop superstars BTS, has earned double platinum certification in the United States.
The Recording Industry Association of America (RIAA) revealed the certification on its website Thursday (U.S. time), adding in a tweet, "Congratulations to @bts_bighit! #Butter is DOUBLE PLATINUM!!"

The awards range from gold certification (500,000 units) to platinum (1 million units), multi-platinum (over 2 million units) and diamond (10 million units).
"Butter" is the septet's second single to earn double platinum after "Dynamite" in March.
