Katy Perry's "Last Friday Night (TGIF)" is the fifth song from her latest album to top Billboard's Pop Songs airplay chart.
That breaks a record previously owned by Lady Gaga and Justin Timberlake, who'd previously had a mere four tunes each from a single album land at No. 1 on that chart, which has been around for 19 years.
But Perry is poised for a far more significant achievement when the Hot 100 is announced later today. Michael Jackson holds the record on that historic chart, having topped it with five singles from his 1987 "Bad" album.
If "Last Friday Night" reaches No. 1 on the Hot 100, as expected, she'll tie Jacko's high mark ... and then, surely, try to outdo it by releasing a sixth single from "Teenage Dream's" treasure trove of smashes.
Meanwhile, Eric Church was indulging in some self-fulfilling prophecy when he titled his third effort "Chief." The upstart country singer turned out to be the commander-in-chief of the latest Billboard 200 album sales chart, as his latest effort debuted on top with 145,000 copies sold -- more than quadrupling the opening numbers for his previous album.
Female singers made most of the news over on the album sales chart, after Church's stately No. 1 bow. Adele fell from the top spot to No. 2, even though, at 83,000, her unit figures were actually up a little, as they have been almost every week.
Kelly Rowland's ultimate career destiny is still a question mark, as her third solo album, "Here I Am," entered at No. 3 on sales of 77,000 units -- a slight comedown for Beyonce's former sidekick, despite the urban ubiquity of her "Motivation" single.
Amy Winehouse's "Back to Black" sold 54,000 and moved up five spots to No. 4, in its first full week of predictably robust posthumous sales. Another white British soul singer, Joss Stone, enjoyed the week's final top 10 entry, as "LP1," her first independently released album, kicked in at No. 9 with 30,000 sold, a slight improvement over her previous major-label-backed effort.
One singles chart that Perry is not currently queen of is digital song sales. The top spot belonged, as it has for a month now, to LMFOA's unstoppable "Party Rock Anthem," which sold another 202,000 downloads. After a slow start last week, Jay-Z and Kanye West's "Otis" jumped up to No. 9 by selling 113,000, setting the stage for next Monday's release of the superstar collaborators' full album, expected to be one of the year's biggest sellers.
