With a potentially [article id="1678211"]huge night on the horizon[/article] at Sunday's Grammy Awards, Adele can start the celebration early if she wants: Her unstoppable 21 will top the Billboard albums chart for a 19th non-consecutive week, according to figures provided by Nielsen SoundScan.

In its 50th week on the charts, 21 moved another 122,000 copies, putting her total sales north of the 6.3 million mark. The next record she's aiming for -- 20 weeks at the top -- is held by Whitney Houston's soundtrack to "The Bodyguard" and Elvis Presley's Blue Hawaii.

A bit further behind was lightning-rod singer [article id="1678704"]Lana Del Rey[/article], whose Born to Die shifted 77,000 units in its chart debut. Poetic music legend Leonard Cohen came in at #3 with Old Ideas (41,000) and gospel singer Fred Hammond rounded out the new faces in the top 10 with God, Love & Romance (26,000).

The rest of the top 10: the 2012 Grammy Nominees compilation (#4, 34,000), Kidz Bop 21 (#5, 30,000), Drake's Take Care (#6, 30,000), Tim McGraw's Emotional Traffic (#7, 29,000), LMFAO's Sorry for Party Rocking (#9, 22,000) and Rihanna's Talk That Talk (#10, 22,000).

One of the week's biggest movers was buzz act Gotye, whose Making Mirrors jumped up 25 spots to #20 on sales of 18,000, while hard-rock legends Metallica's Beyond Magnetic 30th anniversary EP sold nearly 14,000 copies to land at #29.

On the iTunes charts, Kelly Clarkson ruled the singles tally with "Stronger (What Doesn't Kill You)," followed by Adele's "Set Fire to the Rain," David Guetta's "Turn Me On," Tyga's "Rack City," Wiz Khalifa and Snoop Dogg's "Young, Wild & Free" and Madonna's "Give Me All Your Luvin'." Rounding out the tally was Flo Rida with "Good Feeling," the cast of "Glee" with "Smooth Criminal," Gym Class Heroes' "Ass Back Home" and Jessie J's "Domino."

The iTunes albums chart belonged to Madonna with pre-orders for MDNA, Del Rey, Adele, the Madonna compilation Celebration, Drake, Gotye, Cohen, Clarkson's, Stronger, [article id="1678637"]Grammy-nominated DJ Skrillex[/article]'s EP Bangarang and the soundtrack to the movie "Drive."

Adele will likely hit the record mark next week, with her only competition coming from reunited rockers Van Halen's comeback album, [article id="1676859"]A Different Kind of Truth[/article], as well as a covers album from Paul McCartney and a new album from The Fray.
