Foo Fighters score their second No. 1 album on the Billboard 200 chart, as their latest studio album, Concrete and Gold, debuts atop the list. The set earned 127,000 equivalent album units in the week ending Sept. 21, according to Nielsen Music. Of that sum, 120,000 were in traditional album sales, which also makes the effort the top-selling album of the week. Concrete and Gold was released Sept. 15 through Roswell/RCA Records. The Billboard 200 chart ranks the most popular albums of the week in the U.S. based on multi-metric consumption, which includes traditional album sales, track equivalent albums (TEA) and streaming equivalent albums (SEA). The new Oct. 7-dated chart (where Concrete and Gold debuts at No. 1) will be posted in full on Billboard's websites Tuesday (Sept. 26). Foo Fighters previously led the Billboard 200 with Wasting Light, which debuted at No. 1 in 2011. In total, the group has notched 12 entries on the list, with eight of those titles hitting the top 10. The band premiered on the tally dated July 22, 1995, with its self-titled album, and reached the top 10 for the first time with its second release, The Colour and the Shape, in 1997.

BTS earns both the highest-charting album ever on the Billboard 200 by a K-pop act, and the genre's biggest sales week. The group beats its own record, as the act's 2016 album, Wings, was previously both the highest-charting K-pop album (debut and peak at No. 26 on the Oct. 29, 2016-dated list) and owner of the biggest sales week for a K-pop title (11,000 copies sold in its debut frame -- all from digital albums). Notably, Wings and Love Yourself: Her are the only K-pop albums that have charted in the top 40. Since the release of Wings, BTS' popularity has grown tremendously in the U.S., so it's not a huge surprise to see the robust sales figure for the new album. For example, the act debuted at No. 1 on the Social 50 chart the same week that Wings entered the Billboard 200. (The Social 50 chart measures the most popular artists on Facebook, Twitter, Instagram, YouTube, Wikipedia and Tumblr.)

Since hitting No. 1, BTS has racked up 40 nonconsecutive weeks atop the list. The group's extraordinary popularity on social networks (and very active fanbase online) led to its first Billboard Music Award win for Top Social Artist back in May. (BTS also befriended dance duo The Chainsmokers at the Billboard Music Awards, which led to the pair's Andrew Taggart co-writing and co-producing a track on BTS' new album.)

It's the first time an album by BTS has American distribution, as the group's previous releases were issued through U.S. digital retailers independently by the group's South Korean label, Big Hit Entertainment. While Love Yourself: Her is currently only available as a digital album in the U.S., a physical CD release is forthcoming. Lastly, BTS' online fan army mobilized in high volume during street week in order to get the word out about the album. The passionate fandom was very focused on achieving high chart placement, as fan-run social media accounts helped fellow BTS fans understand how Billboard's charts are compiled, and how sales and streams impact the Billboard 200 during an album's first week, and so forth. (Some fans even went so far as to gift the album to friends via Apple's iTunes Store in order to spread the word. However, sales of any specific album purchased on iTunes and gifted to another are not reported to Nielsen Music by Apple, and thus, do not count on Billboard's charts.)
