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 I.Y.A.Z. are still in the lead with singles "Bed Rock" and "Replay," and the rest of the line-up has also remained fairly stable. New features from Lloyd Banks ("Beamer, Benz or Bentley") and Lil Jon ("Miss Chocolate") make their chart debut at #14 and #17, while T-Pain's "Reverse Cowgirl" and I.Y.A.Z. latest effort, "Solo", graduate from the R&B Chart to claim fifth and 13th place. 50 makes the jump from last week's Rap Chart with "Do You Think About Me," grabbing #18.
