Confident (single): +900k.
Cool for the Summer: +860k (last update in 2015)
Confident (album): +200k in the USA, +500k WW.

Confident (the song) sold over 850k. So yes, it is.

Since you were talking about single's success. It's not a bad total at all. DW by Ariana, which is considered a moderate hit, will probably end up with similar sales... So.... bye

Confident outsold CFTS

It did. (they are probably both around 900k anyway). But CFTS was way bigger in streaming, according to our estimations it is very close to double platinum with streaming.

So you see, a peak position isn't everything. Demi is also very unlucky, since CFTS missed top 10, Confident missed top 20 and the album missed #1 on Billboard. All of them with a very small gap....

leave demi alone.

well i was expecting it sales to be in 600K

Yep.

Confident is confirmed to have passed the 900k sales, CFTS is probably close to the 900k mark too.

Yeah cause your comparison with Demi is fair too
I would have understood if you had compared them with Bea Miller who was on the same X Factor season as them. But Demi?, someone who debuted like 6 years before them? Nah. You just want to make Demi look like a flop when she really isn't.
