Taylor Swift notches her fifth non-consecutive week atop The Billboard 200 with "Fearless" (Big Machine), which moved 90,000 copies in the United States, according to Nielsen SoundScan.

That's a 66% sales slide from the previous week's sum, marking the first time a No. 1 album has sold fewer than 100,000 units since the Feb. 3, 2008 chart, when Alicia Keys' "As I Am" shifted 61,000.

Beyonce's "I Am ... Sasha Fierce" (Music World/Columbia) stays put at No. 2 for a second week with 77,000, a 64% decline. Kanye West's "808s and Heartbreak" (Roc-A-Fella/Def Jam) slips 57% to 71,000 but bumps up 5-3. The Chop Shop/Atlantic soundtrack to "Twilight" moves 66,000 (-56%) and rises 6-4.

Nickelback's Roadrunner album "Dark Horse" descends 4-5 with 64,000 (-64%), while Britney Spears' "Circus" (Jive) falls 3-6 with a couple hundred copies fewer than that, also at 64,000 (-68%). On a 58% decline to 54,000, Keyshia Cole's "A Different Me" (Geffen) keeps the No. 7 spot warm for a second week.

Jamie Foxx's "Intuition" (J) ascends 9-8 on a 57% decline to 45,000. The multi-label "NOW 29" hits compilation flip-flops with it, slipping 8-9 with 44,000 (-64%).

An anomaly amongst overall post-holiday declines, Hollywood Records' "All Wrapped Up" experiences a 112% sales surge, catapulting the album 88-10. The Target exclusive, which features Christmas songs from the Jonas Brothers and Miley Cyrus, among others, shifted 40,000 and was deeply discounted after the holiday season.

The only album to bow inside the top 50 of The Billboard 200 is "The 99 Most Essential Beethoven Masterpieces" (X5 Music Group) at No. 29 with 21,000 copies. The collection sold for just $1.99 at Amazon.com's MP3 store.

At 8.50 million units, sales are down 50% compared to the same total last week and off by 6% compared to the same week last year.
