K-pop super band BTS wrote iTunes chart history Saturday with its new album, "Map of the Soul: 7," topping the iTunes album charts in 91 countries and regions, the band's management agency said.

As of Saturday morning (Korean time), "Map of the Soul: 7" landed atop the iTunes "top album" charts in 91 countries and regions, including the United States, Canada, Britain, France, Italy, Russia, India, Japan and Saudi Arabia, according to Big Hit Entertainment.

This marks the broadest iTunes chart dominance for any BTS album, Big Hit said.

The album's lead track, "ON," also topped iTunes "top song" charts in 83 countries and regions including the US, Canada, Italy, Japan and Egypt, adding to the band's iTunes chart victories.

About five more tracks from the new album, including "Filter," also made the top 10 of the iTunes top song charts in the US and Britain.

The septet dropped the 20-track album a day earlier, kicking off another round of its globally-acclaimed musical journey.

The lead song, "ON," was an immediate hit in the group's home country, topping the real-time single charts by all the five major music streaming services, including Melon and Genie Music. One day after the release, "ON" was still atop the charts. 

The new album also made album sales history in South Korea, selling more than 2.65 million copies on the first day of its release on Friday. That was the biggest volume of first-day album sales for any BTS album and exceeded the sales of 2.13 million copies recorded in the first week by the previous BTS album, "Map of the Soul: Persona."

It took only two hours this time for "7" to surpass the previous first-week sales of 2.13 million copies, Big Hit said.

About one day after the release of the music video of "ON," it collected nearly 44 million views on YouTube.

Also on Saturday, another BTS music video, "Spring Day," topped 300 million YouTube views, the 12th BTS music video to have collected more than 300 million views on the video-sharing platform, according to Big Hit. (Yonhap)
