Flo-Rida’s Mail on Sunday leads this week’s new debuts and will be the only new Hip-Hop album to crack the top 10 of Billboard’s Top 200 album chart. While the Carol City native has enjoyed enormous success with his T-Pain assisted single “Low,” the song’s popularity failed to translate into major sales. Mail on Sunday moved 86,100 copies and will land at No. 4, right behind fellow Floridian and last week’s big winner and Rick Ross. The Boss’s Trilla sold another 90,300 units and moves down two slots to No. 3. Next up we have Atlanta native Rocko with his debut LP Self Made. On the strength of his single “Umma Do Me,” the Def Jam MC sold just under 28,000 CDs and will snag the No. 21 spot. Sheek Louch also charted this week with his third solo album Silverback Gorilla. While his single “Good Love” has enjoyed moderate success at radio, Louch will bow at No. 41 with about 17,800 in total sales. In related news, Gnarls Barkley—the duo consisting of former Goodie Mob MC Cee-Lo and producer Danger Mouse—managed to move 31,000 copies of their latest, The Odd Couple. Those numbers are relatively good considering the album’s release date was bumped up at the last minute and the last week’s release was strictly digital. The physical CD officially landed in stores yesterday (March 25).
