It looks like Big Machine/Republic's Taylor Swift will remain on top of the chart with "Bad Blood" but don't blink, because Ultra/Columbia's OMI is climbing fast with "Cheerleader," and could sneak in under the wire. The Weeknd's "Can't Feel My Face" (XO) has moved up to #3 with no signs of slowing down and should be in a three-way battle for #1 next week with Omi and Taylor. Rachel Platten's uplifting anthem "Fight Song" (Columbia) is within striking distance of the Top 10 and should make it there next week. Beluga Heights/Warner Bros. star Jason Derulo joins the Top 30 with "Cheyenne" while Shawn Mendes' "Stitches" (Island/Republic) and R.City f/Adam Levine's "Locked Away" (Kemosabe/RCA) gain enough momentum to join the Top 30. Finally, this week's Greatest Gainer 5 Seconds of Summer (Capitol) debuts on the chart with "She's Kinda Hot".
