BOYLE AND GAGA RING IN NEW DECADE

Syco/Columbia’s Susan Boyle retains her year-end sales explosion by finishing at #1, as I Dreamed a Dream adds another 131,330 to her total, which now tops 3.1 million in its record-shattering sixth week in the lead.

That’s enough to turn back Interscope Grammy contender Lady Gaga’s deluxe edition of The Fame, which logs another 84k at #2, while the Fame Monster EP is #11, with 43k.

Three more divas round out the week’s Top 5, in J/RMG’s Alicia Keys (#3, 71k), Big Machine’s Taylor Swift (#4, 61k) and Geffen’s Mary J. Blige (#5, 57k).

Island/IDJ teen phenom Justin Bieber continues his impressive showing at #6, followed by Rhino’s Alvin & The Chipmunks: The Squeakquel soundtrack (#7), Interscope’s Black Eyed Peas (#8), Columbia’s Glee, Vol. 1 (#9) and Universal Republic’s Owl City (#10).

Aside from Boyle and Glee, Vol. 2, Steve Barnett’s Columbia team has the first volume of the Glee soundtrack at #17, John Mayer’s Battle Studies at #18 and Grammy nominee Beyonce’s I Am… Sasha Fierce at #39.

Eminem’s new deluxe Relapse: Refill album on Shady/Aftermath/Interscope climbs back into contention at #13, while labelmates Robin Thicke’s Star Trak/Interscope effort, Sex Therapy, is #20 with 50 Cent’s Before I Self Destruct at #33.

Glassnote’s acclaimed Phoenix album, Wolfgang Amadeus Phoenix, is picking up steam at #29, thanks to its appearance on a slew of year-end critics’ lists, while Epic sports three different Michael Jackson releases in the Top 50, including This Is It (#23), Number Ones (#31) and Essential (#47).

Disney’s Hollywood Records is also showing sales clout, landing Selena Gomez and the Scene (#26), Breaking Benjamin (#42) and Miley Cyrus (#43) in the Top 50.

Hitting retail this week is RCA/RMG’s Ke$ha, whose debut album, Animal, looks like it has a shot at #1 next Tuesday, spurred by the 2 million-plus downloads of the hit single, “TiK ToK" and surprisingly good reviews, including this one by L.A. Times pop music critic Ann Powers this morning.
