Billboard is tracking every surprise song BTS has performed during encores on their ARIRANG World Tour, which kicked off on 9 April 2026 in Goyang, South Korea and marks the group's first performances together in four years. The 85-date, 34-city tour supports their chart-topping album ARIRANG, with each night's setlist featuring 16 main songs plus seven encore tracks, two of which change nightly to keep fans guessing.

The surprise picks span the band's whole career, from Hot 100 hits such as "Take Two" to decade-old singles like "I NEED U", and even rarities such as "Crystal Snow" that hadn't been played live in years. Stops so far include Goyang Stadium, Tokyo Dome and Raymond James Stadium in Tampa, with fans online compiling running lists of which tracks have and haven't yet been played.
