already? this track was released forever ago in the US, it's just been a really gradual climber
i think it broke the 1m barrier before it even broke the top 20 on the h100
i think they're overestimating with that number. 2 weeks ago, billboard just reported that it was at 2.5-2.6 million in sales (according to Soundscan), and there's no way that it's passed 3 million yet (seeing as she's been selling a little less than 130-140K per week).
but it will definitely cross that threshold very soon.
