A PREVIEW OF RADIO CHART PREVIEWS

Sia will remain at the top of the T40 chart this week with "Cheap Thrills" (Monkey Puzzle/RCA) while Mad Decent/Def Jam's Major Lazer f/ Justin Bieber and MØ becomes the Greatest Gainer with "Cold Water," as the song is poised to debut near the Top 15.

At Rhythm YMCMB/Republic’s Drake is the king once again with “Controlla" at #1 while his own feature collaboration—DJ Khaled's “For Free” (We The Best/Epic)—leaps to #3 with an increase of more than 300 spins. This sets up the argument that Drizzy could potentially replace himself at #1, thus solidifying his earlier claim that this would be "Summer Sixteen."

And at Modern Rock, it's a tight battle for #1 and at press time, Blink 182's "Bored To Death" and Red Hot Chili Peppers' "Dark Necessities" (Warner Bros.) was too close to call. But it's safe to say if the Chili's don't clinch it this week they will next, which will become their record setting 13th #1.
