BTS has made a successful comeback with their fifth studio album 'Arirang', receiving positive feedback from prominent international media outlets. Rolling Stone praised the group for emphasizing their identity and Korean roots while exploring bold and new musical realms. They noted how the unique experiences of the seven members have come together even stronger, contributing to their unified sound.

Additionally, NPR highlighted that while idol groups evolve, true teams create their own mold, validating 'Arirang' as a work that encapsulates BTS's musical identity. Rolling Stone's UK edition awarded the album a perfect score, praising BTS's impressive artistic caliber and cultural significance. The Guardian also remarked on the refreshing creativity and energy that defines the team.

The title track 'Swim' has been positively reviewed as well, with Billboard calling it the album's anchor and Hollywood Reporter describing it as a pivotal expression of the group’s forward momentum. BTS's comeback concert in Gwanghwamun received similar acclaim, with BBC emphasizing the significance of their return, while the New York Times noted the innovative nature of their Netflix livestream as a new benchmark for pop star career expansion. However, some critiques pointed to the album's overall completeness, suggesting that while 'Swim' holds appeal, the latter half of the album might feel repetitive in tone and impression.
