Michael Jackson's unexpected death last week spurred sales of the pop icon's music to the extent that the three best-selling albums in the US this week, as well as the top nine entries on Billboard's Top Pop Catalog Albums chart, are works from the late performer.

Fittingly, Jackson's best-of set "Number Ones"--which, the week prior to his death, sold 4,000 copies--claims the No. 1 spot on the Top Pop Catalog Albums chart after logging sales of 108,000 copies, according to Nielsen SoundScan retail data. "The Essential Michael Jackson" and "Thriller" follow at Nos. 2 and 3 with sales of 102,000 and 101,000, respectively.

The same three albums would top The Billboard 200 were it not for the fact that catalog albums are ineligible to appear on that chart; the No. 1 slot will instead go to Black Eyed Peas' "The E.N.D.," which sold 88,000 copies. It is the first time that a catalog album has outsold the current No. 1 entry on The Billboard 200, according to the publication.

Meanwhile, filling out the Top Pop Catalog Albums chart's subsequent six slots are 1979's "Off the Wall" at No. 4 with 33,000 copies sold; the Jackson 5's "The Ultimate Collection" at No. 5 with 18,000 copies; 1987's "Bad" at No. 6 with 17,000 copies; 1991's "Dangerous" at No. 7 with 14,000 copies; 2001's "Greatest Hits: HIStory -- Volume 1" at No. 8 with 12,000; and the 2004 box set "The Ultimate Collection" at No. 9 with 11,000 copies.

In all, Jackson's solo albums sold a combined total of 415,000 copies, a sharp contrast to the 10,000 copies logged the week prior to his death, according to Billboard. That total also represents a 40% increase over what Jackson's entire catalog had sold through the first 25 weeks of 2009, Billboard reported.

Jackson also claims the top four slots on the Top Digital Albums chart, and six out of that chart's Top 10 entries.

Other noteworthy milestones include sales of 2.3 million digital tracks, making Jackson the first artist to sell 1 million or more tracks in a single week. That translates into 36 Jackson solo entries on the Top 200 Digital Songs chart (plus six additional Jackson 5 cuts).

Unsurprisingly, radio airplay of Jackson's music skyrocketed following news of his death; Nielsen BDS, which monitors airplay from over 1,600 terrestrial and satellite radio stations and cable music channels, noted a 1,735% increase in plays of songs by the performer.
