Officially unstoppable, the disc moved another 156,000 copies last week to easily keep the #1 position, with sales now north of 1.7 million, according to figures provided by Nielsen SoundScan.
The new faces in the crowd are way in the distance, with "Saturday Night Live"-spawned comedy rap trio Lonely Island floating in at #3 with their second star-studded effort, Turtleneck & Chain (68,000), followed by Christina Perri's long-awaited debut, Lovestrong (#4, 58,000), and Odd Future mastermind Tyler the Creator's Goblin at #5 (45,000).
Reunited '80s new wavers the Cars had a solid #7 (36,000) debut with Move Like This, their first album together in nearly a quarter century.
The rest of the top 10: NOW 38 (#2, 68,000), the Beastie Boys' Hot Sauce Committee Part 2 (#6, 42,000, down 67 percent), Fleet Foxes' Helplessness Blues (#8, 34,000, down 62 percent), Jennifer Lopez's Love? (#9, 33,000, down 60 percent) and Jason Aldean's My Kinda Party (#10, 28,000).
Justin Bieber's modest-selling Never Say Never — The Remixes gets a major boost from the DVD release of his concert movie, moving up 21 spots to #11 on sales of 28,000 as sales picked up by 89 percent. Soul revivalist Raphael Saadiq's Stone Rollin' has a solid bow at #14 (21,000), while rockers Manchester Orchestra hit #21 with their latest, Simple Math (18,000). "Glee" star Matthew Morrison's self-titled debut has a modest arrival at #21 on sales of 16,000.
Adele's total domination continues on the iTunes charts as well, where 21 rules the roost once again, beating out Lonely Island, Perri, Tyler the Creator, the "American Idol" top four digital compilation, the Beastie Boys, Mumford & Sons' Sigh No More, the "Glee"-boosted Rumours by Fleetwood Mac, Fleet Foxes and Manchester Orchestra.
On the iTunes singles chart, Adele's "Rollin' in the Deep" was tops, beating out Gaga's third pre-album release single, "The Edge of Glory," as well as Pitbull's "Give Me Everything," Bruno Mars' "The Lazy Song" and Katy Perry's "E.T." Coming in at #6 is "American Idol" judge Jennifer Lopez's "On the Floor," just ahead of the Black Eyed Peas' "Just Can't Get Enough," Enrique Iglesias' "Dirty Dancer," Lady Antebellum's "Just a Kiss" and Chris Brown's "Look at Me Now."
Things should be fairly static next week, with new releases from New Boyz, Seether, Ben Harper and "Celebrity Apprentice" finalist John Rich, but expect a big shake-up soon with the May 23 release of Lady Gaga's Born This Way.
