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 and Ludacris once again dominate our Top Picks chart, spending another week in (respectively) first and second place with "Bed Rock" and "How Low Can You Go." Lupe Fiasco, Pitbull, and 50 Cent make the jump from last week's Rap Chart, taking 7th, 15th and 17th place with "I'm Beaming," "Pearly Gates" and "Do You Think About Me." Graduating from the R&B Chart to take spots 8, 11 and 18 are Lloyd ("Get a Room"), Jah Cure (Unconditional Love") and Usher ("Little Freak"). Two new features make their debut in the Top Picks Chart: T-Wayne collabo "You Know What It Is" lands at #9, while Kevin Rudolf's "I Made It" hangs on at 20th.
