“The Neptunes Present … the Clones,” the second album from producer-songwriters Chad Hugo and Pharrell Williams along with an army of superstar guests, debuted at No. 1 for the week ended Sunday on sales of 249,262 copies.

Star Trak/Arista album’s lead single, “Frontin’,” featuring Jay-Z, is No. 1 on the R&B/hip-hop singles chart for a second week as follow-up tracks “Light Your Ass on Fire” with Busta Rhymes and the Kelis and Nas duet “Popular Thug” pick up steam.

Rap dominated the charts this week as “Unleashed” (Sony), the third album from Bow Wow, debuted at No. 3 with 120,000 sold; T.I.’s “Trap Muzik” (Grand Hustle/Atlantic) sold 109,000 copies to land one slot lower; and Juelz Santana’s debut “From Me to You” (Roc-A-Fella), bowed at No. 8 on 74,000 units sold.

The soundtrack to “Chicago,” buoyed by last week’s release of the film on DVD, moved up 90 chart positions to No. 6, repping an increase in sales of 550%. “Bad Boys II” (Bad Boy/Universal) remains the top-selling soundtrack even though it slipped below the 100,000 mark for the first time in its six-week stay in the top 10.

Jessica Simpson, fresh off her “Just Married” series on MTV, made it in at No. 10. Last week’s chart-topper, Alan Jackson’s “Greatest Hits Vol. II” (Arista Nashville), fell to No. 2 on sales of 158,000 copies. It remains the top-selling country album.

Punk rock band Rancid had its best week ever, as “Indestructible” debuted at No. 15 with sales of 51,000. Country singer Sara Evans also had a career best: Her RCA disc “Restless” sold 44,000 copies and landed at No. 20. Alien Ant Farm’s sophomore album “truANT” (DreamWorks) sold 27,000 copies and Adema’s third album “Unstable” (Arista) was a notch lower at No. 43.

Top 25 albums saw sales jump 13% from last week; the top 200 were up 12%. Compared with the similar period last year, however, top 25 sales are down 4% and the top 200 is about even.
