For the week of January 16-22, BTS member Jimin's hit track "Who" held steady at No. 13 on the Official Singles Chart, widely regarded as the UK equivalent of Billboard's Hot 100.

The track has now spent a remarkable 20 weeks on the chart, surpassing PSY's "Gentleman" to become the second longest-charting K-pop solo song of all time. Only PSY's iconic 2012 hit "Gangnam Style" has maintained a longer run.

Including songs by K-pop groups, "Who" ranks as the fourth longest-charting K-pop track in the history of the Official Singles Chart, following "Gangnam Style", BTS's "Dynamite", and FIFTY FIFTY's "Cupid".
