Eminem extends his "Encore," as the album picks up a second consecutive week atop The Billboard 200, with U.S. sales down 54% from last week to 198,000, according to Nielsen SoundScan. This is the Shady/Aftermath/Interscope set's fourth non-consecutive week at the summit.

In the wake of the holidays, sales drop considerably this week, allowing Green Day's "American Idiot" (Reprise) to rocket 9-2 despite a 40% slide to 170,000. With a 15-3 leap, Lil Jon & the East Side Boyz's "Crunk Juice" (TVT) sees the smallest decline of the top 10, down 34% to 144,000.

"MTV Ultimate Mash-Ups Presents Jay-Z and Linkin Park: Collision Course" (Machine Shop/Roc-A-Fella/Def Jam) rises 8-4 on a 52% drop to 135,000 units, while Ludacris' "Red Light District" (Disturbing Tha Peace/Def Jam South) moves 10-5 on a 51% fall to 126,000. A 63% drop is enough to keep Usher's "Confessions" (LaFace/Zomba) steady at No. 6 for the second week, with 117,000 copies.

R&B newcomer John Legend bows at No. 7 with his studio debut, "Get Lifted" (Sony Urban Music/Columbia). The former session piano player enters with 116,000 copies.

Tupac Shakur's "Loyal to the Game" (Amaru/Interscope) moves up 13-8 despite a 41% slide to 115,000.

The only top-10 albums to drop positions this week are the 17th installment of "NOW That's What I Call Music!" (Sony BMG/Universal/EMI/Zomba/Capitol), down 2-9 on a 68% dip to 113,000 copies, and Destiny's Child's "Destiny Fulfilled" (Sony Urban Music/Columbia), down 4-10 on a 70% slide to 105,000.

Fox/Epic/Sony's "Garden State" soundtrack is The Billboard 200's Greatest Gainer, as one of only three albums on the chart with a sales bump. After last week's DVD release, the set jumps 133-51 on a 31% gain to 37,000. The soundtrack to "The Phantom of the Opera" (Really Useful/Sony Classical/Sony) also rises, moving 104-44 on a 9% increase to 40,000. Snow Patrol's "Final Straw" (A&M) rounds out the sales gainers, up 192-91 on a 14% rise to 20,000.

Overall U.S. album sales plummet 51% from last week to 15.9 million units. Because of an extra sales week this year, there is no comparison with last year's tracking period. This fact helps the 2004 total, which is up 3.8% over 2003, at 681 million units.
