Sia’s “On” appearance follows several other recent high-profile collaborations by BTS, who have worked with the likes of Halsey, Ed Sheeran, The Chainsmokers, Desiigner, Steve Aoki, Lauv, and Nicki Minaj on a variety of tracks since 2017.
Aside from the single, Map of the Soul: 7 features other previously unheard of new songs from BTS, including “My Time, “Louder Than Bombs,” and “We Are Bulletproof: the Eternal.” The latter is an apparent sequel to “We Are Bulletproof” and “We Are Bulletproof, Part 2,” songs released by BTS both prior to and on their debut album 2 Cool 4 Skool back in 2013. The track offers a throwback to seven years ago, when BTS was at the very start of their career.
Shortly after the tracklist arrived, Troye Sivan announced on Twitter that he co-wrote "Louder Than Bombs."
Following the release of the tracklist, several hashtags inspired by it, including #7TRACKLIST, trended worldwide on Twitter as BTS’ dedicated fan ARMY celebrated the news.
Map of the Soul: 7 is set to be released worldwide on Feb. 21 at 4AM EST.
