R&B star Usher landed his fourth Number 1 album this week as his latest effort, "Looking for Myself," debuted atop the latest edition of the Billboard 200 with 128,000 copies sold.  However, the sales for "Looking" were not as impressive as the sales for Usher's previous three studio albums, and were the fewest first-week sales for an Usher album since his 1997 set "My Way" debuted with 67,000 copies sold.
