South Korean boy band BTS finally made their comeback with their fifth studio album, Arirang, by releasing the lead single titled Swim. This marks their first full-group release in years following their military service. Featuring Hollywood actress Lili Reinhart in the music video, the song is an upbeat alternative pop/R&B track exploring themes of hope and navigating life's waves. Soon after the music video was dropped, fans flooded the social media platforms to give their views.
The song ‘Swim’ focuses on moving at your own pace and staying afloat. The track has generated massive online engagement and mixed, passionate reactions from netizens. Despite the reaction, there is overwhelming excitement that all seven members are back together for their first album in three years.
One user wrote, 'According to BTS members, ‘SWIM’ is the most minimal track in the album; its not a song that instantly grabs your attention, but it has a long lasting impact and grows on you. They tried to create a song better than SWIM as a title track for a month, but SWIM just felt the most natural. Its simple yet appealing."
Another user wrote, 'Swim is an upbeat alternative pop track and it took BTS a long time to come up with that title. it is also a song for ppl who simply swims day by day and the tannies hope it becomes our strength as we move forward with our life. F*** MY LIFE IS OVER IT’S A TEARJERKER.”
"Bangtan were not joking when they said the more you listen to the album the more your favourite song changes cos wdym i went from loving body to body to normal to swim to hooligan LIKEEE", wrote the third user.
