Beyonce racks up her second No. 1 on The Billboard 200 with "B'Day," bypassing her best one-week sum by more than 220,000 copies. The Columbia set moved a whopping 541,000 units in its first week, according to Nielsen SoundScan, the best sales number since Tool's "10,000 Days," sold 564,000 in May. "B'Day" also scores the No. 1 position on the Top R&B/Hip-Hop Albums tally.

Beyonce also topped The Billboard 200 with her solo debut, "Dangerously in Love," which sold 317,000 in its first week. Only one Destiny's Child album managed a bigger start, 2001's "Survivor" with 663,000.

Audioslave's third full-length effort, "Revelations" (Epic) bows at No. 2 with 142,000 and caps the Top Rock Albums chart. The group's sophomore effort, 2005's "Out of Exile," fared better on the big chart, debuting at No. 1 with 263,000.

After crowning the chart for the first time in 30 years last week, Bob Dylan's "Modern Times" (Columbia) slides to No. 3 with 128,000, a sales hit of 33%. Danity Kane's self-titled Bad Boy effort follows suit, falling 2-4 with 82,000 (-30%). The soundtrack to Disney's "The Cheetah Girls 2" climbs a notch 6-5 despite a 15% sales decrease, with 68,000.

Christina Aguilera's RCA album "Back to Basics" slips 4-6 with 64,000, a sales decline of 36%. Jessica Simpson's "A Public Affair" (Epic) drops 5-7, with 60,000 and a sales descent of 41%.
