Congrats are in order for Ghost as their new Popestar EP has debuted atop of Billboard's Top Rock Albums Chart. And while a chart-topper is reason enough for celebration, the fact that Popestar is the first EP ever to accomplish the feat makes it all the more special.

According to Billboard, the EP sold 21,000 in its first week, bolstered by the band's new single "Square Hammer." The set also includes covers of songs by the Eurythmics, Echo and the Bunnymen, Simian Mobile Disco and Imperiet.

The Rock Albums Chart was launched in 2006 and this marks the band's second offering to top the chart, with the full length Infestissumam previously doing so in 2013. Last year's Meliora album peaked at No. 2 on the Rock Albums Chart.

It's been a big year for Ghost, who started off 2016 winning a Grammy for Best Metal Performance for the song "Cirice" from the Meliora album. The band have toured extensively in support of the disc, and now have the Popestar EP to promote as well. See their current dates here.
