No surprise here: Taylor Swift tallies a record-extending fifth week at No. 1 on the Billboard Artist 100 chart.

The Artist 100 provides the first weekly ranking dedicated to measuring artist activity across Billboard's most influential charts, including the Billboard Hot 100 songs chart, Billboard 200 albums chart and the Social 50. The Artist 100 blends data measuring album and track sales, radio airplay, streaming and social media fan interaction to provide a weekly multi-dimensional ranking of artist popularity.

Swift stays at the summit despite a 12 percent loss in overall points. Album sales, for her three-week Billboard 200 No. 1 1989 and her prior albums, continue to contribute her largest share of points (47 percent), as 1989 sold 312,000 copies in the week ending Nov. 16, according to Nielsen SoundScan, a 22 percent downturn. Last week, album sales marked 63 percent of her Artist 100 sum.

Taylor Swift Makes Hot 100 History With 'Blank Space'

In addition to her (modest) decline in sales for 1989, also helping erode the share of album sales is the surge of single "Blank Space," which blasts 13-1 on the Hot 100 following the Nov. 10 release of its official video. Last week, Swift's streaming and digital songs sales accounted for 5 and 22 percent of her Artist 100 points, respectively. This week, those numbers swell to 9 and 32 percent. Led by "Space," Swift's airplay also rises, from 6 to 8 percent.

Notably, for a third week, Swift tops the Artist 100, Hot 100 and Billboard 200 simultaneously. No other act has led Billboard's three signature charts at the same time.

Below Swift on the Artist 100, Foo Fighters debut at No. 2, as their new album Sonic Highways starts at No. 2 on the Billboard 200 with 190,000 copies sold. Pink Floyd starts at No. 3, also fueled by its new set, The Endless River, which begins on the Billboard 200 at No. 3 (170,000).

Maroon 5 (3-4) and Sam Smith (4-5) round out the Artist 100's top five.

Meanwhile, a glance throughout the Artist 100 confirms that the holiday season is upon us. Pentatonix powers 83-29, with album sales contributing 81 percent of the vocal quintet's chart points, as That's Christmas to Me spends its fourth week at No. 1 on Top Holiday Albums. The set, which reaches a new Billboard 200 peak (23-8), is the holiday chart's Greatest Gainer, dashing by 131 percent to 34,000.

Michael Buble likewise (sleigh) rides holiday album sales to Artist 100 action, as he debuts on the list at No. 70. Album sales mark 94 percent of his Artist 100 palette, as his 2011 chestnut Christmas climbs 5-2 on Top Holiday Albums (26,000, up 223 percent).

Buble also brings the first holiday song of the season to the Adult Contemporary chart. His and Idina Menzel's "Baby It's Cold Outside," from her new seasonal release Holiday Wishes (24,000, up 109 percent), debuts on the airplay ranking at No. 25. Menzel bounds 70-43 on the Artist 100.
