We should have known better: never underestimate the chart prowess of Katy Perry. Back in May, we predicted that Perry’s single “Last Friday Night (T.G.I.F.)” would continue the chart run of singles from the album, and sure enough, Thursday will mark the 66th straight week in which a Teenage Dream single was in the top ten of Billboard‘s Hot 100. Two weeks ago, though, we cast doubt on the prospect of “Last Friday Night (T.G.I.F.)” hitting #1—and in so doing, tying what once seemed like an untoppable Michael Jackson record: five #1 singles from the same album, set with “I Just Can’t Stop Loving You,” “Bad,” “The Way You Make Me Feel,” “Man in the Mirror,” and “Dirty Diana,” all from Bad, in 1987 and 1988.
That was before the Missy Elliott remix. On this we’ll defer to the Village Voice, where, in April, Maura Johnston pointed to the late-release remix as a growing chart-goosing tactic and noting its particular success for Perry with “E.T.” (#42 before its Kanye “remix”; #1 soon after). Then on Friday, Chris Molanphy explained in his chart column “100 & Single” exactly how Perry was juking the stats: releasing a Missy Elliott remix of “Last Friday Night (T.G.I.F.),” last Monday, as the song was peaking on the Airplay chart but falling on the Digital Sales chart (the two figures combine to determine the Hot 100), and furthermore discounting all versions of the track to just 69¢ at iTunes and Amazon’s mp3 store.
It worked. “Last Friday Night (T.G.I.F.)” nearly matched LMFAO‘s “Party Rock Anthem” in Digital Sales this week (with the remix accounting for 25% of the downloads) and remained atop the Airplay chart. Despite huge gains in airplay and especially sales for Maroon 5‘s “Moves Like Jagger,” featuring Christina Aguilera, the single could not (yet?) match up to Perry’s single (nor could either of the other songs we predicted might compete; Bad Meets Evil‘s “Lighters” has stalled at #5, and The Throne‘s “Otis” is already out of the top 10). So it came down to LMFAO, who simply could not extend their reign atop the Hot 100 to a seventh week. This news may leave Michael Jackson fans thinking the electro duo should have named their album Sorry For Not Party Rocking Enough.
