It's low debut is due to a lack of streaming not airplay. Canada doesn't have the stupid streaming rule and if I'm right CMB isn't doing well on radio there as well but still debuted at #25 on the Canadian Billboard Hot 100.
Mr.know It All debuted at #18 with 107,000 downloads and about 6million of airplay and #8 on the digital chart.
Catch My Breath debuts at #54 with 87,000 downloads, 3million of airplay and #11 on the digital chart.
If the streaming rule was non-existing CMB would've debuted in the 20-25 range just like in Canada. Getting a Top 20 and Top 10 hit on the billboard hot 100 isn't as easy anymore.
So I've made a calculation:
One Person can play CMB 360 times in 24 Hours
One Person can play CMB 2520 times in a week.
10 of us can play the song 25200 times in a week.
20 of us can play the song 50400 times in a week.
30 of us can play the song 75600 times in a week.
75,600 streams = 76 X 0.1 = 8 points
87,000 sales = 87 X 1 = 87 Points
6Million airplay = 6 X 1.5 = 9 Points
Total = 104 Points
You have to have around 240 points to hit Top 10 and +400 points to hit #1 right now.
So as you see, if we would decide to do a streaming marathon or something, it wouldn't necessary help. We should only do the streaming marathon when she's close hitting the top 10 by a few points or the #1 spot. Right now it would be a waste of time
The streaming rule is a ****ing nightmare
I mean what are the damn odds of meeting someone that's in the business and from the same small town that you're from? And is the stepson of your idol? Her life is like the craziest luck. 
So WBT was the #1 song when SUBG was #2?
Can we wed? 
(Bieber, One Direction, Taylor, Nicki Minaj) it's very sad.
