Fans are still clamoring for the musings of their favorite MTV reality star, as Ashlee Simpson's Geffen debut "Autobiography" reclaims the top spot of The Billboard 200.

The season finale of "The Ashlee Simpson Show" helped the singer grab this week's greatest-gainer honors and her second week at No. 1 with a 5% U.S. sales increase to 286,000 copies, according to Nielsen SoundScan.

The set ousts the 16th installment of the "Now That's What I Call Music!" series from the No. 1 slot. A 45% sales slide to 276,000 ends the one-week reign of the Universal/EMI/Sony Music/Zomba compilation, which falls to No. 2 this week.

Simpson's debut single "Pieces of Me" is also the fastest-growing track on both the Billboard Mainstream Top 40 and Adult Top 40 charts. The song climbs to No. 2 and No. 19, respectively.

Jimmy Buffett's former chart-topper "License to Chill" (Mailboat/RCA) climbs 4-3 with a 13% drop to 101,000 copies, while Usher's "Confessions" (LaFace/Zomba) also climbs a spot to No. 4 with a 10% slide to 96,000.

Gretchen Wilson's "Here for the Party" (Epic) jumps 6-5 on an 8% drop to 89,000 sold and Avril Lavigne's "Under My Skin" is right behind at No. 6. Even with a 2% drop to 73,000 this week, the Arista artist jumps back into the top 10 after falling 7-11 last week.

As Prince continues his trek for latest set "Musicology," he climbs back into the top tier at No. 7. With sales rising 21% to 73,000, the NPG/Columbia artist's strategy of including a copy of the album with each concert ticket moves him up from last week's No. 15 position.

Maroon 5 climb seven spots to round out the top 10 with "Songs About Jane," which gains 14% to 61,000 copies.

In the wake of last week's maelstrom of new titles, only four debuts make the top half of the big chart. Disney's "The Princess Diaries 2: the Royal Engagement" soundtrack leads the pack at No. 27 with 33,000 copies. Jazz saxophonist Boney James sells 17,000 to enter the chart at No. 66 with his latest Warner Bros. studio set "Pure." At No. 80, veteran country artist Randy Travis' "The Very Best of Randy Travis" (Rhino) opens with 15,000 copies. Finally, rap act Crime Mob makes its self-titled BME/Reprise/Warner Bros. debut on the Billboard 200 at No. 90 with 14,000 sold.

Overall U.S. album sales were down 6.5% to 11.4 million, about 8.4% ahead of the comparable week last year. Sales for the year are ahead of those of 2003 by about 7.5%.
