This is the most substantial update to the chart's methodology since May of 1991, when Billboard first used Nielsen's point-of-sale data — SoundScan — to measure album sales.
As previously reported, the new Billboard 200 chart uses accepted industry benchmarks for digital and streaming data, where 10 digital track sales from an album is equivalent to one album sale, and 1,500 song streams from an album equates to one album sale. All of the major on-demand audio subscription services are considered, including Spotify, Beats Music, Google Play and Xbox Music.
Swift's return to No. 1 is powered by 339,000 total album equivalent units in the week ending Nov. 30. Of that sum, the majority is pure album sales (281,000).
1989's album sales now stand at 2.5 million after five weeks on sale.
The album is also No. 1 on the Top Album Sales chart, which maintains the old Billboard 200's methodology of ranking pure album sales.
Swift continues to ride high on the Digital Songs chart, where she has two songs in the top 10: "Blank Space" (holding at No. 1, with 342,000 downloads; up 13 percent) and "Shake It Off" (8-10 with 93,000; up 12 percent).
Back on the Billboard 200, a cappella group Pentatonix hits a new high as its album That's Christmas To Me rises 3-2 with 227,000 units. It also climbs 3-2 on Top Album Sales with 217,000 (up 119 percent).
The new Shady XV compilation album arrives at No. 3 on the Billboard 200, with 148,000 units (138,000 album sales). The set celebrates the 15th anniversary of Eminem's Shady Records and its hit singles like 50 Cent's "In Da Club," Eminem's "Lose Yourself" and D12's "Purple Pills."
Shady XV is the second top 10 compilation from Shady Records, following 2006's Eminem Presents: The Re-Up, which debuted and peaked at No. 2.
Last week's Billboard 200 champ, One Direction's Four, slips to No. 4 with 125,000 units in its second week. (Of that sum, 105,000 are album sales -- down 68 percent from its launch of 387,000.)
Sam Smith's In the Lonely Hour bounds 11-5 with 123,000 units (97,000 pure album sales).
Rick Ross nabs his seventh consecutive top 10 studio album as Hood Billionaire bows at No. 6 with 79,000 units. On the Top Album Sales chart, it starts at No. 6 as well, with 74,000 copies sold. Hood Billionaire is the rapper's second studio effort in 2014, following the No. 1 debut of Mastermind (179,000 in album sales). His previous set, 2012's God Forgives, I Don't, also started at No. 1 (218,000).
Flying 39-7 on the new Billboard 200 is a clear beneficiary of the chart's new methodology: Ariana Grande's My Everything. It moved 72,000 units for the week, heavily powered not just by album sales (47,000), but also track equivalent albums (19,000) and streaming equivalent albums (6,000).
Had the new Billboard 200's methodology not been in place, My Everything would have ranked at No. 16 (where it stands on the Top Album Sales chart). My Everything has been absent from the top 10 on the Billboard 200 since its third week on the list (dated Sept. 27, when it fell 4-11).
Beyonce's new Beyonce: More Only (EP) struts in at No. 8 on the Billboard 200 with 71,000 units. The digital set includes only the new bonus material (new songs, remixes and videos) that was added to the deluxe reissue of her self-titled album. The new EP sold 43,000 albums, but also garnered 25,000 in TEA and another 3,000 in SEA.
On the Top Album Sales chart, the Beyonce: More Only (EP) launches at No. 17.
The diva's self-titled album also scoots up both lists, thanks to its expanded reissue. On the Billboard 200, Beyonce rises 199-39 (25,000 units), while on the Top Album Sales chart, it vaults 199-37 (22,000 album sales; up 713 percent).
Closing out the top 10 on the new Billboard 200 is the surging Frozen soundtrack (13-9 with 71,000 units) and Maroon 5's V (32-10 with 68,000 units). This is Frozen's first week in the top 10 since the Sept. 20-dated chart. Maroon 5's album charges up the list thanks to sale pricing at retailers during the busy Thanksgiving shopping week (including in the iTunes Store, where it was offered for $6.99).
