“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.

Jimi Hendrix’s People, Hell And Angels enters The Billboard 200 at #2, just behind Luke Bryan’s Spring Break…Here To Party. This puts the rock legend back in the top five 42-1/2 years after he died at age 27. No other artist in chart history has cracked the top five this long after his death. Elvis Presley is in second place. His Elvis: 2nd To None debuted at #3 in October 2003, a little more than 26 years after his death.

This is the highest ranking for an album by a performer who had passed away since Whitney Houston’s Whitney: The Greatest Hits logged three weeks at #2 in the weeks following her death in February 2012. The last album by a deceased performer to reach #1 was Michael Jackson’s This Is it soundtrack, which debuted at #1 in November 2009.

People, Hell And Angels is, incredibly, Hendrix’s 35th posthumous album to make The Billboard 200. The album consists of 12 previously-unreleased studio recordings which Hendrix recorded between 1968 and 1970.

Hendrix was a star for just three years, from June 1967, when he played the Monterey International Pop Festival, to September 1970, when he died in London of a drug overdose. Here’s a sign of just how long Hendrix has been gone: All of the other artists in this week’s top 10 were born after Hendrix died.

If a song is potent enough to enter the Hot 100 at #1, you might expect that it’s likely to settle in for a long run in the top spot. In recent years, for whatever reason, it hasn’t worked out that way. Of the last 10 songs to debut at #1, just two have snagged a second week on top: Lady Gaga’s 2011 smash “Born This Way” (which spent its first six weeks at #1) and Baauer’s “Harlem Shake” (which holds at #1 for the second week).

“Harlem Shake” debuted at #1 last week, concurrent with Billboard’s decision to add YouTube video streaming data to the Hot 100 mix. The song amassed 98 million streams this week (down 5% from last week’s staggering total of 103 million). Still, that’s more than 10 times as many streams as the song at #2: “Thrift Shop” by Macklemore & Ryan Lewis (featuring Wanz), which amassed 9.5 million streams. Streaming data is just one element in the Hot 100 mix, but it’s obviously going to be an ever-more-important one.

“Americana” music—an industry term for rootsy, guitar-based music—accounts for three of the top six albums on this week’s Billboard 200. Mumford & Sons’ Babel holds at #1 for the fifth week, The Lumineers’ The Lumineers jumps from #6 to #5 its 47th week and Alabama Shakes’ Boys & Girls leaps from #20 to #6 in its 43rd week. (Sales of Boys & Girls jumped by 10% compared to last week. It’s the only album in the top 15 to show a sales increase.)

Babel and The Lumineers were both nominated for Best Americana Album at the Grammys on Feb. 10. (They lost, in a big surprise, to Bonnie Raitt’s Slipstream.) Boys & Girls had also been entered in that category, but it wasn’t nominated. (It doubtless would have made the finals if the voting had occurred just a few weeks later).
