The band earns its second leader, following "Square Hammer."
The Swedish hard rock act first led Mainstream Rock Songs with "Square Hammer," which ruled for two weeks in January-February 2017.
"Rats" reaches No. 1 in its 12th week on the chart, after "Hammer" took 17. Ghost had charted two prior titles on the tally: "Cirice" (No. 4, 2015) and "From the Pinnacle to the Pit" (No. 5, 2016).
Meanwhile, "Rats" ranks at its No. 14 high on the all-rock-format Rock Airplay chart for a second week, reaching a new-best 5.2 million audience impressions (up 1 percent) in the tracking week, according to Nielsen Music. "Rats" is now one spot off Ghost's top peak on Rock Airplay, as "Hammer" hit No. 13.
"Rats" is the lead single from Prequelle, Ghost's fourth studio album, released June 1. It became the band's second No. 1 on Top Rock Albums, launching with 66,000 equivalent album units on the June 16-dated tally, also good for the band's highest-charting album (No. 3) on the all-genre Billboard 200.
