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.

Longtime reader favorite B.o.B adds a #1 Booth smash to his resumé this week, bumping last week's top two, Young Money's "Bed Rock" and Lil Wayne's "Drop the World," down to second and third place. Young Money signees Tyga and Drake, however, gain their label two spots in the countdown, snapping up #8 and #9 with "I'm on It" and "Over." Also making their chart debut in our Top Picks lineup are Bobby Valentino (with the Nicki Minaj-assisted "Stilettos & T-Shirt," at #17) and Young Jeezy (with Plies collab "Lose My Mind," at #18. I.Y.A.Z.' "Solo" and Luda's "Sexting" graduate from last week's R&B and Rap charts (respectively) to come in fifth and 19th.
