BTS's "Swim" Dropped Three Spots. Arirang Didn't Move.
The single is sliding. The album isn't.
"Swim," the lead track from BTS's fifth studio album Arirang, fell to No. 5 on the Billboard Hot 100 for the week of April 18 - down three spots from the previous week. At the same time, Arirang held No. 1 on the Billboard 200 for a third consecutive week, extending a run that has no parallel in K-pop history. No Korean act has held the top album spot for three straight weeks. The last group to do it at all was Mumford & Sons with Babel in 2012.
The numbers aren't contradictory. They describe the same audience doing two different things. "Swim" is declining on the Hot 100 because radio play and streaming activity for the single have normalized after the initial surge. Arirang is holding because fans are still listening to the full 14-track album - not just its lead single. According to Billboard's April 18 chart data, six of the album's fourteen tracks remained on the Hot 100 for a third straight week: "Body to Body" (No. 52), "2.0" (No. 67), "Hooligan" (No. 72), "NORMAL" (No. 82), and "FYA" (No. 90) alongside "Swim." All thirteen vocal tracks placed in the top 50 of the Global 200.
"Swim" also led digital song sales for the third consecutive week, moving 24,000 downloads - a metric that tracks intentional purchases rather than passive streams. On the Hot 100, where radio airplay carries significant weight and BTS's US radio footprint remains limited compared to domestic pop acts, a drop from No. 2 to No. 5 in two weeks is a predictable trajectory, not a collapse.
Arirang debuted with 532,000 equivalent units in its first week - the highest opening for a group album since Billboard began separately tracking that metric in December 2014. The album has since held No. 1 on Spotify's Weekly Top Albums chart for three consecutive weeks, returned to the top of Germany's Official Top 100 Albums, placed No. 2 on France's SNEP chart and Australia's ARIA Top 50, and charted No. 2 and No. 3 on Japan's Oricon weekly digital and combined album rankings.
The chart run is landing while BTS is on the road. The group completed three opening shows of the BTS World Tour 'ARIRANG' at Goyang Stadium on April 9, 11, and 12, drawing approximately 132,000 attendees across the three nights. Fans in 194 countries joined through live viewings and Weverse streams. The tour is the largest K-pop concert cycle announced for 2026-2027, with dates confirmed across Asia, North America, Europe, Latin America, and Oceania.
RM, who co-wrote the lyrics for "Swim" and took a lead role in shaping the album, described the project at a pre-release press conference: "These 14 tracks are the answer to the question, 'What is BTS in 2026?'" The album's title pulls from the traditional Korean folk song Arirang, which has historically carried meanings of separation, longing, and return - a frame that tracks directly with the group's four-year gap for military service, now fully concluded.
The next set of ARIRANG tour dates are scheduled for North America beginning in June.
