That third #1 on Pop is definitely going to happen.
However, what they need is a form of promo. Hopefully, when Selena gets on stage for the Kid's Choice Awards, they'll play a portion of the song. I mean, this song should've been her BIGGEST hit yet and they're really not doing anything about it.
At least it already has done moderately well for a third single! Not a lot of artists can say that for themselves!
