Welcome to the Booth's Top Hip Hop and R&B Chart! As always, your feedback has determined which songs made the cut. Each chart’s lineup is calculated using a special DJBooth.net Formula that takes into account member ratings and reviews as well as features’ overall popularity.

Young Money's reign at #1 with "Bedrock" continues, but Virgin Islands-bred buzzmaker I.Y.A.Z. pushes Luda's "How Low" down one spot to grab second. The only new feature to debut on this week's Top Picks Chart, Hova, Rihanna and Bono's Haiti-dedicated "Stranded" lands at 12th. Pole-vaulting up from last week's R&B lineup are Omarion and Jason Derulo who claim #8 and #14 with singles "Speedin'" and "In My Head," while B.o.B.'s "Nothing On You" and Yo Gotti's "Women Lie, Men Lie," hop from the upper reaches of our Rap Chart to land at #16 and #18.
