*The sole new feature to earn a spot on the chart, Kat Dahlia's "Mash It Up" debuts in 15th.
*Previously "Next Up," Nelly's "Rick James" enters the chart in 18th.
*French Montana's "F**k What Happen Tonight" makes its exit from our charts.
*Big K.R.I.T.'s "Just Last Week," Benni Haze's "It's on Me" and Chase & Status's "Machine Gun" narrowly miss appearing on the chart. Your feedback and ratings will determine whether they make the cut next week!
