The top slot on the nation’s album sales chart changed owners for the fourth time in as many weeks as country singer LeAnn Rimes landed at No. 1 Wednesday with her latest offering.

Rimes’ third album, “You Light Up My Life,” not only topped the pop album chart, but also led the country and contemporary Christian listings as well. It was the singer’s second album to be released this year. In February, “Unchained Melody: The Early Years” bowed.

Rimes, who turned 15 three weeks ago, saw her Curb Records album of inspirational songs — which includes “God Bless America” — sell nearly 186,000 copies during the seven-day period ended Sept. 14.

The bow marks her second consecutive No. 1 bow on the pop charts, where all three of her discs reside in the chart’s top 100. More than 232,000 albums and 91,000 singles bearing Rimes’ name were sold during the sales tabulation period.

“LeAnn has demonstrated the vibrancy that exists in the music industry today,” Curb Group exec veep/G.M. Dennis Hannon said.

Rapper Master P slipped one notch to No. 2, as his No Limit Records disc “Ghetto D” sold more than 156,000 copies. His tally was almost halved from the disc’s first-week numbers.

Other discs that dropped a notch during the week included Puff Daddy’s Bad Boy/Arista Records disc “No Way Out,” with 128,500 copies, and Fleetwood Mac’s Reprise Records set “The Dance,” with 115,000 copies.

Jewel again checked in at No. 5 with 97,000 copies of her Atlantic Records debut “Pieces of You” being sold.

Notable entries this week included gospel crossover singer Amy Grant’s “Behind the Eyes” coming in at No. 8, and Danish group Aqua’s debut release “Aquarium,” which opened at No. 15 on sales of 55,000 copies.

Sales of the disc were undoubtedly helped in part by the publicity surrounding the lawsuit filed by Mattel against MCA Records over the group’s satirical hit song “Barbie Girl.”

Rounding out the top 10 were Trisha Yearwood’s MCA Nashville disc “Songbook: A Collection,” which logged 87,000 copies; “Spice” by Virgin Records’ Spice Girls at No. 7 on sales of 84,000 copies; Grant at No. 8; Atlantic Records act Matchbox 20′s “Yourself or Someone Like You” slipping to No. 9 on sales of more than 79,000 copies; and Prodigy, whose Maverick Records disc “Fat of the Land” went home with 71,000 consumers.
