It's going to come down to the wire as to whether RCA can lift G-Eazy's "No Limit" to #1, and push out Post Malone's "Rockstar" (Republic) this week—currently too close to call, but feels like it will happen. Meanwhile, Camila Cabello's "Havana" f/Young Thug (SYCO/Epic) will be up over 500 spins and makes a drive inside the Top 10. Columbia has two records climbing quickly upwards, Calvin Harris' "Faking It" and N.E.R.D. & Rihanna's "Lemon." Look for Yo Gotti's "Juice" (CMG/Epic) to debut this week, and watch for G-Eazy f/Halsey's "He & I" (RCA) to have a great weekend of airplay.
