“Dynamite” became BTS’ first No. 1 hit on the Billboard Hot 100 chart when it was released last year. After years of logging Top 40 hits and selling out arenas and stadiums, the seven-member collective is competing for best pop duo/group performance and will also perform at Sunday’s (March 14) show. BTS is the first K-pop act to compete at the Grammys. “It’s really hard to express in words,” Jimin said of the nomination. “Even now we can’t still believe that we were nominated, and we’ll be able to perform at the Grammys. So, we’re thankful. We’re honored.”
