Welcome to the Booth's recently-expanded 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.

Jason Derulo's Imogen Heap-sampling hit, "Whatcha Say," and Birdman's Weezy/Drake-assisted "Money to Blow" are still going strong in the top two, but the rest of the lineup's been shuffled considerably. Three new features, Gucci Mane's "Wasted (Remix)," Luda's Battle of the Sexes buzz track "How Low Can You Go" and Rihanna's latest single, "Hard," debut at spots four, six and 12, while Rap Chart graduates 50 ("Psycho"), Wiz Khalifa ("This Plane") and Drake ("I'm Going In") grab #5, #17 and #20.
