If US Billboard was the same like it was a few years ago, Your Body would've charted around the same like in Canada in its 1st week.
Anyways #13's an amazing starting point in Canada.
Ah! I was crossing my fingers for a top ten debut in Canada! That chart is known for it's high debuts. Not Myself Tonight debuted at #11 so I was almost certain it would crack the top ten! At least we have our first top twenty charting?
I was a little worried when YB was rising slower than in every other country, but she's holding pretty well.
