“Thrift Shop” by Macklemore & Ryan Lewis featuring Wanz sold 4,178,000 copies in the first quarter of 2013. That’s more, by far, than any song has sold in the first quarter of a calendar year in digital history. The old record was set last year, when “We Are Young” by fun. featuring Janelle Monae sold 2,753,000 copies in the first quarter.

“Thrift Shop” logs its sixth week at #1 on the Hot 100. That’s the longest run since Bruno Mars’ “Locked Out Of Heaven” spent six weeks on top in December and January. It’s the longest run by an ongoing duo (not just a one-time collabo) since LMFAO’s “Party Rock Anthem” (featuring Lauren Bennett & Goon Rock) had six weeks on top in the summer of 2011.

“Thrift Shop” tops Hot R&B/Hip-Hop Songs for the 12th week. That enables it to surpass Robin Thicke’s 2007 hit “Lost Without U” for the longest run at #1 by a white artist since the chart originated (as Harlem Hit Parade) in October 1942. (Mariah Carey, whose “We Belong Together” logged 14 weeks at #1 on the R&B chart in 2005, is biracial. Her father was of African American and Venezuelan descent. Her mother is of white Irish descent.)

Two other songs by the duo are moving up the Hot 100. “Can’t Hold Us” jumps from #27 to #15 in its eighth week. “Same Love” (featuring Mary Lambert) re-enters the chart at #93. The latter song has already climbed as high as #89.

“Thrift Shop” by Macklemore & Ryan Lewis featuring Wanz returns to #1 on the Hot 100 after logging five weeks at #2 behind Baauer’s viral phenomenon “Harlem Shake.” It’s the first song to return to #1 after such a long absence since Chubby Checker’s “The Twist,” which returned to #1 in January 1962, 16 months after it first topped the chart.

“Thrift Shop” rises to #1 even though it falls to #2 on both Hot Digital Songs (behind “Just Give Me A Reason” by P!nk featuring Nate Ruess) and Hot Radio Songs (behind Bruno Mars’ “When I Was Your Man”). How’d that happen? “Harlem Shake” fell off even more sharply. Billboard’s Gary Trust reports that “Thrift Shop” dropped by 6% in overall chart points, while “Harlem Shake” dropped by 28%.

“Thrift Shop” tops the 5 million mark in digital sales this week. The song sold 5 million copies in 30 weeks. Just three songs in digital history have reached 5M faster: “Somebody That I Used To Know” by Gotye featuring Kimbra (23 weeks), Carly Rae Jepsen’s “Call Me Maybe” (24) and “We Are Young” by fun. featuring Janelle Monae (28).

“Thrift Shop” by Macklemore & Ryan Lewis featuring Wanz is #1 on Hot Digital Songs for the 10th straight week. It’s #1 on the all-genre Radio Songs chart for the second week. Under the old chart formula, that would make the genial hip-hop smash a virtual lock for the #1 spot on the Hot 100. But under the new formula, which gives great (and I would contend excessive) weight to YouTube streaming data, it ranks #2 for the fifth straight week, behind Baauer’s “Harlem Shake.” That viral phenomenon is #6 on Hot Digital Songs and has yet to crack the 75-song Radio Songs chart. (Given that its total radio audience shrank by 9% this week, it probably never will crack the Radio Songs chart.)

“Harlem Shake” makes up for its deficits in sales and radio airplay by holding at #1 on the Streaming Songs chart for the fifth week. But even here it is losing its mojo. Its total streams drop by 42% this week, from 48 million to 28 million. (By comparison, the streaming total for “Thrift Shop” is 9.5 million, which represents a gain of 4% compared to last week.)

The streaming total for “Harlem Shake” has been shrinking every week since it debuted, from 103 million to 98 million to 54 million to 48 million to 24 million.

Billboard’s Gary Trust reports that, in terms of overall Hot 100 points, “Harlem Shake” has a 29% lead over “Thrift Shop” this week. But that’s down from a 103% lead last week.

This tells us four things. 1. “Thrift Shop” may return to #1 on the Hot 100 next week (though it will also have to contend with Bruno Mars’ new smash). 2. Billboard should seriously consider whether it thinks “Thrift Shop” should have spent the last five weeks at #2. Maybe its run at #1 should have been interrupted for a couple of weeks, when the “Harlem Shake” phenomenon was at its peak, but this sustained shut-out seems excessive. 3. Billboard probably should have had a longer trial run period, to get the new chart mix just right. 4. It’s to Billboard’s credit that it is being so transparent about the numbers behind the numbers. It's not trying to hide anything.

David Bowie’s The Next Day enters The Billboard 200 at #2, becoming the rock icon’s highest-charting album to date. It tops Station To Station, which peaked at #3 in February 1976. Even so, it was no match for Bon Jovi’s What About Now, which debuts at #1. It’s the band’s fifth #1 album.

Bowie is one of the most celebrated artists of the rock era. He made the cover of TIME in 1983, was inducted into the Rock and Roll Hall of Fame in 1996 and received a Grammy Lifetime Achievement Award in 2006. Bon Jovi hasn’t received any of those accolades. The band just sells albums (and concert tickets) year in and year out.

What About Now is the band’s third consecutive studio album to hit #1. It follows 2007’s Lost Highway and 2009’s The Circle. This marks the first time that the band has hit #1 with three consecutive studio albums.

Bon Jovi is the third act from New Jersey to amass five or more #1 albums. The band trails Bruce Springsteen, who has had 10 #1 albums between 1980 and 2012, and Frank Sinatra, who had six between 1946 and 1966. Whitney Houston is in fourth place. She had four #1 albums between 1986 and 2009. (Bon Jovi, which demonstrated its state pride by titling its 1988 album New Jersey, is from Sayreville, N.J. Springsteen was born in Freehold, Sinatra in Hoboken and Houston in Newark.)

This marks the second time that Bon Jovi has annoyed rock critics by debuting at #1 ahead of a critically-lauded act. Lost Highway debuted at #1 in June 2007, beating out the White Stripes’ Icky Thump, which debuted and peaked at #2.
