The kings of K-pop, the BTS group, released a new album on Friday, which broke records by becoming the most pre-ordered album in South Korea and the first single to be released on Tiktok.

BTS (abbreviation of Bangtan Sonyeondan, which means "Boy Scouts resistant to bullets") is a worldwide musical phenomenon.

It is the first K-pop group to have reached the charts in the United States and in Great Britain and chained sold out concerts in Los Angeles, Chicago or London, or even ignited in June a Stade de France completely full.

Their album "Map of the Soul: 7" was released around the world at the same time, Friday at 6:00 p.m. in Seoul (9:00 GMT).

This figure refers to the number of group members as well as the number of years that have passed since their inception.

The group presented a 30-second extract of their single "ON" exclusively on Thursday on the short video sharing application TikTok, causing a bug.

BTS is the first group to present their single via TikTok and fans were invited to use the sound of the song to create their own videos.

As of Friday morning, over 33,000 videos have already been made using this title. You could see fans dancing there in places such as classrooms.

The song "ON" is "like a newspaper from our past five years," BTS member Apple Music RM told Apple Music RM.

This album is already the most ordered of all time, with more than 4.02 million copies sold.

"We have actually expanded our musical range," said RM. "In 2013, we performed in front of 300, 500 people, but now we are touring the stadiums, where everything is bigger and happier," said the group member.
