Ludacris earned his third No. 1 this past week with the release of his latest, 'Release Therapy,' selling 309,000 copies, according to Nielsen SoundScan. That was more than enough to knock Justin Timberlake from the top spot, whose 'FutureSex/LoveSounds,' dropped to No. 5 with another 146,000 copies sold, which thrust the former *NSYNC-er to platinum status in just three weeks.

Janet Jackson edged in behind Luda at No. 2, selling 296,000 copies of '20 Y.O.' and earning her eighth straight Top 3 debut. Tony Bennett scored his highest charting debut ever at No. 3 (201,000 copies) with his 'Duets: An American Classic,' which features collaborations with John Legend, Diana Krall, Elton John and Paul McCartney, among others.

Rounding out the Top 5 was the fourth debut of the week, Alan Jackson's 'Like Red on a Rose,' which sold 148,000 copies, landing the country star his ninth Top 10 effort.
