BTS: What's up New York? BTS.</s>VAUSE: That was the K-Pop sensation BTS thanking supporters after hitting a major milestone for South Korean music. Their new song "Dynamite" reached the number one spot on the Billboard Hot 100 this week making them the first South Korean group to ever top the U.S. charts.</s>UNIDENTIFIED MALE: I'm seeing with my own eyes, it feels like I'm still dreaming and dreaming. Thanks to everyone who has worked on this track and of course, mostly more than anything -- thank you, thank you, thank you, thank you. I love you.</s>VAUSE: For the record, before this week, the highest spot any South Korean song had ever reached was number 2. It was back in 2012 "Gangnam Style". Oh, the horror. Thank you for watching CNN NEWSROOM. I'm John Vause, thanks for the company. CNN's Robyn Curnow has more after a short break.
