Well, it looks like there will be a #1 and #2 by the same artist on the Pop Chart for the first time since 2004 as Shawn Mendes' "Senorita" f/Camilla Cabello (Island/Epic-Republic) and Shawn's "If I Can't Have You" (Island/Republic) will slide into the two top spots. Congratulations to the Republic and Island staffs on a job well done! New to the chart this week will be RCA's Normani "Motivation."
