BTS's Jimin shot up to the top of the iTunes Top Songs charts in 112 regions worldwide with his latest solo music, "Who."

"Who," the lead track off of his second solo album, "Muse," was released on Friday and topped the iTunes' most popular songs chart in 112 regions, including the United States, Britain, Canada and Germany.

The song also sat on the No. 1 spot on the Worldwide iTunes Song chart and the European iTunes Songs charts. Six out of all seven tracks from the album made it to the top 10 list on the Worldwide iTunes Song chart.

The album also topped the iTunes Top Albums chart in 87 regions worldwide, including the United States and Britain.

"Muse" comes as the BTS singer's first new solo album in a year and four months since releasing "Face" in March last year.

The album tells the story of Jimin's effort to find love and the ordeals he faces along the way, according to his agency, BigHit Music.

"I focused on letting Jimin's feelings get across in the music while he was working," Pdogg, the BTS music producer, said in a press release on Friday. "The song's tracks have been arranged to follow his very flow of emotion. It will be fun to listen to it in that order."

Jimin began serving his military duty in the Army's 5th Infantry Division Artillery Brigade last December and will be discharged on June 11 next year.

"Jimin is an artist whose efforts make him so attractive," Pdogg said. "We started working on 'Muse' as soon as the work for 'Face' ended, and it made me think, 'You're working this hard when you're just about to start your duty?' Such effort has matured his music, and you can see exactly what it is."
