It's too close to call as to whether Childish Gambino's "Redbone" (Glassnote) will rise from #3 to #1 this week, since DJ Khaled's "I'm The One" (We The Best/Epic) is currently occupying the top spot—but knocking him out could be a matter of 50 spins or less. Meanwhile, French Montana's "Unforgettable" (Epic) and DJ Khaled's other heat-seeker "Wild Thoughts" featuring Rihanna & Bryson Tiller (We The Best/Epic), continue to explode. Def Loaf's "No Fear" (Columbia) will have a 500+ spin increase again this week, and will be the highest debut on the chart. And look for Fifth Harmony's "Down" f/ Gucci Mane (Syco/Epic) to debut as well.
