*Drake's "Worst Behavior" drops from first to second, unseated by Katy Perry's newly-released "Dark Horse (Remix)." The former runner-up, will.i.am's "Feelin' Myself," graduates to our Top Hip Hop and R&B Chart.
*B.o.B's "Throwback," an ex-Top Pick, lands in third.
*Debuting this week along with Perry's joint, Jennifer Lopez's "Girl," Young Thug's "Danny Glover (Remix)," IAMSU!'s "Only That Real" and Kirko Bangz's "Hoe" enter the chart in ninth, 11th, 12th and 13th.
*Kat Dahlia's "Mash It Up," G-Eazy's "Been On (Remix)" and Young Chris's "Fouled Out" narrowly miss appearing on the chart. Your feedback and ratings will determine whether they make the cut next week!
