BTS returns from hiatus with Swim, a global chart-topping anthem facing legal scrutiny
In short: After a four-year military service hiatus, BTS returned in 2026 with the lead single Swim. The track became an immediate international success, topping charts from the United States to Germany. Yet, beneath the nautical-themed visuals and synth-pop melodies, the group now faces a copyright lawsuit regarding the song's origins.
Released on March 20, 2026, as the lead single from the album Arirang, Swim marked the highly anticipated comeback of BTS. The song, written by a team including RM, is an English-language synth-pop track characterized by a tempo of 92 to 96 beats per minute. RM described the lyrics as an exploration of the confusion surrounding the group's transition through military service, aiming to offer listeners a sense of warmth and resilience. The song’s cultural impact was immediate, with its music video—directed by Tanu Muiño and featuring Lili Reinhart—trending at number one in 70 countries within an hour.
The commercial performance of the track was historic. In the United States, it debuted at the top of the Billboard Hot 100, becoming the group's seventh song to reach that position. It also set records in Germany, where BTS became the first group to simultaneously hold the number one spot on both the album and singles charts with new entries. Despite this success, the song became the subject of a legal dispute in July 2026. Plaintiffs filed a complaint in a California federal court, alleging that the track incorporated protected elements from an unpublished 2025 demo. The lawsuit seeks damages and an injunction against the song's continued use.
Big Hit Music has formally denied these allegations, maintaining that Swim is an entirely original composition. As of July 2026, the case remains active with no judicial ruling on the merits of the claims. While the legal battle continues, the song remains a central part of the group's Arirang World Tour. The project has also expanded into a broader cultural initiative, including a mini-documentary titled Keep Swimming that profiles prominent figures like director Park Chan-wook, further cementing the song's role as a multifaceted artistic statement for the band.
