The song is the second original single from the K-pop supergroup following the release of ‘Dynamite’ last year.

The new track will arrive on May 21 at 5am BST and is described in a statement as being “a dance pop track brimming with the smooth yet charismatic charm of BTS.”

‘Dynamite’ recently became the longest-charting single by a Korean artist on the Billboard Hot 100. BTS’ record surpassed a 31-week run by Psy in 2013 for ‘Gangnam Style’.

‘Dynamite’ also became the longest-running number one on Billboard’s Digital Song Sales Chart. It surpasses an achievement previously attained by Luis Fonsi’s ‘Despacito’, which topped the chart 17 times.
