Janet Jackson [ tickets ]’s “All for You” trounces the competition in its first week of release to land in the No. 1 spot on the album chart. Albums from country artist Tim McGraw [ tickets ] and R&B singer Case also post Top 10 debuts.

“All for You” (Virgin), Jackson’s first album since 1997’s “The Velvet Rope,” moved just over 605,000 copies during its debut week, according to industry sources. The album features the hit title-track, which itself sits at the top of the Billboard Hot 100 singles chart, a spot that it has held for four weeks straight.

Trailing “All for You” by a considerable margin with sales of just over 220,000 copies is McGraw’s “Set This Circus Down” (Curb/Atlantic), the country star’s second album in as many years. The album’s track “Grown Men Don’t Cry” is up two spots to No. 5 on trade publication Radio & Records’ latest Country national airplay chart.

“NOW That’s What I Call Music! Vol. 6” (Epic) finally relinquishes its No. 1 position after spending the previous three weeks in the top spot. The album--which features previously released hits from Backstreet Boys, ‘NSync, Britney Spears, Destiny’s Child, Shaggy [ tickets ], U2, Lenny Kravitz and others--dips to No. 3 this week.

Clocking in at No. 4 is the latest posthumous release from rapper Tupac Shakur [ tickets ]. “Until the End of Time” (Interscope), a collection of 29 previously unreleased songs, is the fourth Shakur album to surface since he was shot to death in 1996.

The third new album in this week’s Top 10 is the No. 5 debut from Case. Sales of “Open Letter” (Def Jam), the R&B artist’s third release, were spurred by the success of the album’s first single, “Missing You,” which is spending its second consecutive week at the top of Billboard’s Hot R&B Singles & Tracks chart.

Dropping three spots to No. 6 this week is Shaggy’s “Hotshot” (MCA), which is followed at No. 7 by Uncle Kracker’s “Double Wide” (Atlantic). The latter disc--the first solo effort from the Kid Rock D.J.--was released last June, and entered the Top 10 for the first time last week at No. 9. The sudden surge comes courtesy of the track “Follow Me,” the No. 7 track on Billboard’s latest Top 40 Airplay chart.

Albums taking a dip this week to fill in the lower rungs of the Top 10 are: “No Name Face” (DreamWorks) from Lifehouse, down two spots to No. 8; “No Angel” from Dido, down one spot to No. 9; and “Country Grammar” from Nelly, down three spots to No. 10.

Making notable debuts further down the chart are: the Bee Gees, whose “This is Where I Came In” (Universal) logs in at No. 16; Fear Factory, whose “Digimortal” enters the chart at No. 32; and the “Ally McBeal” soundtrack (Epic), which bows at No. 34.

Ducking out of the Top 10 after debuting there last week are: Brooks & Dunn’s “Steers & Stripes” (Arista), which falls from No. 4 to No. 18; and Sunshine Anderson, whose “Your Woman” (Atlantic) drops to No. 15 from No. 5.
