*Last week's front-runners retain the top two, but switch positions, with ScHoolboy Q's "Collard Greens" climbing to first and Wale's "Bad (Remix)" tumbling to second.

*Kid Ink's "Money & Power," Wale's "Rotation," J. Cole's "New York Times," French Montana's "F**k What Happen Tonight" and Ace Hood's "We Outchea" graduate from last week's Rap Chart to claim fourth, seventh, eighth, ninth and 17th.

*Up from our R&B/Pop Chart, Chris Brown's "Don't Think They Know" and Pharrell Williams' "Happy" claim 12th and ninth.

*Formerly part of our Club Chart, French Montana's "F**k What Happen Tonight" and B.o.B's "Headband" snag 16th and 17th.

*Juicy J's "One of Those Nights," Machine Gun Kelly's "Peso" and ASAP Ferg's "Work (Remix)" narrowly miss appearing on the chart. Your feedback and ratings will determine whether they make the cut next week!
