*After overtaking Aaliyah's "Enough Said" to claim first last week, Game's "Celebration" retains its spot atop the chart. G.O.O.D. Music's "Clique" hangs on in second.
*No new features debut on the chart, but several records from our genre-specific charts earn placement. Making the jump from last week's Rap Chart, Lil Wayne's "No Worries," Talib Kweli's "Congregation," and B.o.B's "Out of My Mind." snag third, sixth, and 14th.
*Graduating from last week's R&B/Pop Chart, Rihanna's "Cockiness (Love It)," Alicia Keys' "Girl on Fire" and Chris Richardson's "Joy & Pain" claim eighth, 13th and 16th.
*Wiz Khalifa's "It's Nothin" makes its exit from the chart.
