Personally I believe Pharrells number could be higher, if not the songs below should at least be:
Don't get me wrong but how is Dark Horse going to drop from 251,000 in sales to 180,000. It has been dropping about 10% each week and that would be about a 28% decrease!

Even Talk Dirty's drop seems too high as well. It's been dropping less than 10% percent each week, and 241,000 to 190,000 is about a 23% decrease
Also I think All Of Me will gain again next week, the songs getting great radio updates and isn't even close to being finished. Last week it sold 203,000 with a 23% increase! it's not going to drop back down to 200,000.
Unless sales are the pits next week, these numbers should all be slightly higher imo
