Jamie Foxx Bumps Mary J. Blige From Billboard‘s #1

Singers swap spots as Ying Yang Twins score the highest chart debut.

The music industry must be glad to be rid of 2005. Overall album sales nosedived a whopping 8 percent from 2004′s figures — the sharpest sales tumble since 2002. And the year didn’t end on a positive note. According to the latest SoundScan figures, all but eight of the week’s 200 biggest-selling records suffered sales declines during the last week of the year — and five of the eight are newcomers to Billboard‘s albums chart.

But that shouldn’t matter much to Jamie Foxx. The Oscar winner turns the tables as his second album, Unpredictable, knocks Mary J. Blige’s The Breakthrough to #2 after taking a backseat to the R&B diva on the previous chart. With nearly 200,000 copies sold, Foxx’s Unpredictable bests week-two sales of Blige’s Breakthrough by close to 7,000.

U.S.A. (Still United), the Ying Yang Twins’ re-imagining of their hit LP U.S.A. (United State of Atlanta), was one of the chart entrants that didn’t finish in the red. U.S.A. (Still United) was also the highest charting of the week’s five debuts, taking the #45 spot with 35,000 scans. Greatest Hits, a collection of songs by late 1950s teen idol Ricky Nelson, opened at #102 with sales of nearly 18,000. Detroit rapper Trick Trick’s The People Vs. Trick Trick debuted at #115 with nearly 16,000 copies sold. The soulful sophomore release from Goapele, Change It All, claims the chart’s #139 position with week-one sales of more than 13,000. And Sevendust’s Best of Sevendust (Chapter One: 1997-2004) opens at #156 with over 11,000 sales.

Panic! At the Disco’s A Fever You Can’t Sweat Out (which finished at #88 with 20,000 copies sold), a Christian music compilation titled Open the Eyes of My Heart (#109, 17,000) and Underoath’s They’re Only Chasing Safety (#183, 9,000) were the only three non-debut discs on the chart to see an increase in sales.

Eminem’s Curtain Call: The Hits climbs one to #3. The rapper’s retrospective release sold close to 186,000 copies, bumping Notorious B.I.G.’s Duets: The Final Chapter to #4 with nearly 150,000 sales. America’s newest “Idol,” Carrie Underwood, holds on to the chart’s #5 post, selling around 135,000 copies of her debut, Some Hearts.

The 20th installment in the Now That’s What I Call Music! compilation series finished in sixth place with 104,000 scans — just enough to relegate Nickelback’s All The Right Reasons to the #7 spot with 103,000 copies sold. Mariah Carey takes #8 this week, selling more than 102,000 copies of The Emancipation of Mimi, and the Black Eyed Peas’ Monkey Business finishes at #9 with more than 97,000 copies sold. Chris Brown’s self-titled debut rounds out Billboard‘s top 10 with 90,000 plus scans.
