The music video of K-pop superband BTS' 2020 megahit single "Dynamite" has topped 2.1 billion views on YouTube, becoming the most-viewed music video by the group, its agency said Wednesday.

The video surpassed the threshold at about 8 a.m., adding 100 million views just nine months after hitting 2 billion in September to become the first music video by BTS to reach 2.1 billion, BigHit Music said.

The first English-language song from the group, "Dynamite" is an upbeat disco pop song carrying a message of hope.

The single topped the Billboard Hot 100 chart, becoming the first song by a K-pop act to reach No. 1 and remain atop the chart for a total of three weeks. It also stayed on the chart for 32 weeks, the longest for a K-pop artist.
