'BTS WORLD' becomes the best-selling Original Soundtrack (OST) in Korea, breaking the 17-year record of the drama 'Winter Sonata'.

The original soundtrack album for BTS's new mobile game BTS World, which came out on June 26, dropped today (June 28), and features the sweeping new single from the group in the form of the expressive “Heartbeat.”

Along with “Heartbeat,” BTS World’s soundtrack also features 10 other brand new tracks, primarily instrumental songs, along with the three previously released collaborative songs that split the group members up among the trio, which saw those groupings collaborate with Charli XCX, Zara Larsson, and Juice WRLD.

The soundtrack also featured songs from two other Korean artists aside from BTS, “You Are Here” by Big Hit Entertainment labelmate and former 8Eight member Lee Hyun, and “LaLaLa” female indie pop duo Okdal, who is under Magic Strawberry Sound.
