Def Jam will hold on to the #1 spot this week with Rihanna's “Needed Me” (Westbury Road/Roc Nation) but of course RiRi's FWB, YMCMB/Republic's Drake, is up on her tail with “Controlla." DJ Khaled's “For Free” f/ Drake (We The Best/Epic) and Calvin Harris f/Rihanna's “This Is What You Came For” (Columbia) continue to build inside the Top 10. RCA's Usher f/Young Thug's “No Limit” and Sia's “Cheap Thrills," along with Republic's Marc E. Bassy with “You & Me” and Ariana Grande's “Into You," all experience significant gains. And look for Nick Jonas' “Bacon” (Island/Republic) to debut this week.
