'Popestar' is also the first EP to reign in the chart's 10-year history.
Swedish metal band Ghost leads Billboard's Top Rock Albums chart (dated Oct. 8) for the first time, as the six-piece's new EP Popestar debuts with 21,000 sold in its first week, according to Nielsen Music.
Notably, the release is the first EP to rule Top Rock Albums in the chart's 10-year history, which dates to 2006. The release includes the original track "Square Hammer" as well as covers of songs by Eurythmics, Echo & the Bunnymen, Simian Mobile Disco and Imperiet.
Popestar also starts as Ghost's second No. 1 on Hard Rock Albums, following Infestissumam, which reigned for a week (May 4, 2013). Meanwhile, 2015's Meliora debuted and peaked at No. 2 on both Hard Rock Albums and Top Rock Albums; it re-enters the Oct. 8 charts at Nos. 15 and 32, respectively, up 402 percent to 2,000 sold.
