POTW: Christina Aguilera, Jay-Z, Pink, Lil Wayne
Rihanna gets "Louder" while performing on MTV's "The Seven" in Times Square in NYC Nov. 15.

FIT FOR A KING: Michael Jackson returns to the Hot 100, as the Akon duet "Hold My Hand" debuts at No. 84. The song concurrently lifts 53-45 on R&B/Hip-Hop Songs and debuts on Adult R&B at No. 16, the chart's highest start this year.

On the Hot 100, Jackson's 48th, and first posthumous, chart entry is his first since "Wanna Be Startin' Somethin' 2008," also with Akon, peaked at No. 81 the week of Feb. 9, 2008.

Until this week, only one other artist had previously teamed up with the King of Pop in multiple Hot 100 visits. Paul McCartney and Jackson reached No. 2 for three weeks in 1983 with "The Girl Is Mine" and spent six weeks at No. 1 beginning that December with "Say Say Say."

Speaking of a Beatle ...

CAN BUY: ... following their long-awaited arrival in the iTunes Store, the Fab Four dominates Billboard's Rock Digital Songs chart.

The Beatles inhabit 39 of the chart's 50 positions, steamrolling past the prior mark of seven concurrent titles, set by Linkin Park last month.

Here is a look at the chart's top 10 Beatles titles:

No. 2, "Let It Be"
No. 4, "Here Comes the Sun"
No. 5, "In My Life"
No. 6, "Hey Jude"
No. 7, "Come Together"
No. 8, "Yesterday"
No. 9, "Blackbird"
No. 11, "Twist and Shout"
No. 13, "While My Guitar Gently Weeps"
No. 14, "With a Little Help From My Friends"

Notably, half the titles above were never released as singles, prompting Billboard associate director of charts/retail Keith Caulfield to suggest that consumers last week sought songs beyond the Beatles' most well-known chart hits to round out their iTunes libraries.

The act that can boast that it blocked the Beatles from No. 1 the chart week that their catalog became available digitally? OneRepublic, which rebounds 2-1 on Rock Digital Songs with "Secrets" for a fourth week on top and first since Sept. 25.

HARRY POTTER AND THE SEVENTH CHARTED SOUNDTRACK: As the penultimate Harry Potter film, "Harry Potter and the Deathly Hallows: Part 1," works its magic across U.S. box offices, its soundtrack debuts on the Billboard 200 at No. 74.

On the Soundtracks chart, the new album begins at No. 4, continuing the franchise's perfect streak of top five peaks.

Here is a look at the Billboard 200 (and Soundtracks) performances of each "Harry Potter" release:

No. 48, "Harry Potter and the Sorcerer's Stone," 2001 (No. 2)
No. 81, "Harry Potter and the Chamber of Secrets," 2002 (No. 5)
No. 68, "Harry Potter and the Prisoner of Azkaban," 2004 (No. 3)
No. 80, "Harry Potter and the Goblet of Fire," 2005 (No. 4)

The series' first three soundtracks were composed by John Williams; the fourth by Patrick Doyle; and, the fifth and sixth by Nicholas Hooper. The newest edition features music composed by Alexandre Desplat and orchestrated by Conrad Pope, the latter of whom previously orchestrated tracks on the first three "Harry Potter" soundtracks.
