Half of the group's 10 top 10s are holiday albums.

Penatonix earns its 10th top 10 album on the Billboard 200 chart, as the group's latest effort, The Best of Pentatonix Christmas, rises 18-8 in its sixth week on the tally. The hits compilation was released via RCA Records on Oct. 25.

The Billboard 200 chart ranks the most popular albums of the week in the U.S. based on multi-metric consumption as measured in equivalent album units. Units comprise album sales, track equivalent albums (TEA) and streaming equivalent albums (SEA). The new Dec. 14-dated chart (where The Best of Pentatonix Christmas climbs 18-8) will be posted in full on Billboard's websites on Dec. 10.

The Best of Pentatonix Christmas earned 43,000 equivalent album units (up 64%) in the U.S. in the week ending Dec. 5, according to Nielsen Music. The Best Of collects favorites from the group’s previous four holiday albums, along with four new songs.

One of the new tracks on The Best Of is a virtual collaboration with Whitney Houston, "Do You Hear What I Hear." The tune is credited to Pentatonix featuring Houston. Houston recorded and released a solo rendition of the song on the 1987 charity compilation A Very Special Christmas. The new version debuted at No. 19 on the most recently published Adult Contemporary airplay chart (dated Dec. 7).

Pentatonix is always a favorite during the holiday season, as of the group’s 10 top 10 albums, five are holiday efforts. Combined, the act's holiday albums have sold 4.5 million copies in the U.S.
