Now that the band has hit the road with their ARIRANG World Tour, supporting their Billboard 200 No. Since kicking off the tour April 9 at Goyang Stadium in Goyang-si, South Korea, BTS has performed surprise songs during every show’s encore. The band has even performed a few tracks it has not played in almost a decade, including “Crystal Snow,” on the ARIRANG World Tour. Fans are of course ecstatic about the possibility of hearing a BTS track performed live for the first time. As BTS continue on their 85-date, 34-city world tour, Billboard will continue to update this list with each new surprise track the band plays.
