Pop singer Taylor Swift continued her reign at the top of the revamped US Billboard 200 album chart on Wednesday, shaking off new entries.

Swift's "1989" album sold 230,000 full copies, 435,000 songs and was streamed 27,000 times, according to figures from Nielsen SoundScan, totaling 274,000 sales units and holding the top spot for a fifth non-consecutive week.

According to the new chart formula unveiled by Billboard last week, 10 songs equal one album unit and 1,500 online streams equals one album unit.

"Shake It Off," Swift's lead song from "1989," scored three Grammy nominations, including two for top categories last week.

At No. 2 this week, a cappella group Pentatonix holds steady with its festive record "That's Christmas to Me" totaling 221,000 units, while veteran rockers AC/DC entered the chart at No. 3 with its latest album "Rock or Bust" topping 174,000 units.

The only other new entry in the top 10 of the Billboard 200 chart was R&B singer Mary J. Blige's "London Sessions" at No. 9.

Swift's song "Blank Space" held the top spot on the digital songs chart with another 254,000 digital downloads, while actress Jennifer Lawrence's rendition of James Newton Howard's "The Hanging Tree" from "The Hunger Games: Mockingjay - Part 1," held steady at No. 2 with 168,000 downloads.
