Christina Aguilera slammed the competition in a debut-heavy sales week, with the soulful star's latest double-disc album, 'Back to Basics,' selling 342,000 copies, according to Neilsen SoundScan. That was more than enough to give Aguilera her first No. 1 since her 1999 self-titled debut.

Soul singer Lyfe Jennings landed at No. 2 with his sophomore effort, 'The Phoenix' -- which includes a re-worked version of 2Pac's 'Keep Your Head Up' and 'Biggie N****,' a tribute to the rap titan's storytelling -- selling 136,000 copies. Taking the No. 3 spot was country singer Trace Adkins, whose 'Dangerous Man,' sold 115,000 copies.

Rounding out the Top Five were Atlanta R&B chanteuses Cherish, whose latest album, 'Underappreciated,' sold 91,000 copies, while following closely behind was the soundtrack to the Disney flick, 'The Cheetah Girls 2,' selling 87,000 copies.
