Drake will hold the #1 spot for another week with "Controlla" (YMCMB/Republic) while competing with himself for #1 with his DJ Khaled collab "For Free" (We The Best/Epic), which is quickly closing the gap. Epic’s Fifth Harmony grows inside the Top 10 with “All In My Head.” RCA's Sia has a sizeable increase powered by her #1 at T40 momentum with “Cheap Thrills." Drake f/Rihanna's “Too Good” explodes while Major Lazer f/ Justin Bieber and MØ's “Cold Water" (Mad Decent/Def Jam) will be up over 700 spins. Look for Kungs vs. Cookin’ On 3 Burners' “This Girl” (Casablanca/Republic) to debut this week.
