It's a lead single and its add date was yesterday. Its updates can be better. You can sit here denying that it's a lackluster update or you can request and help it get even better updates.
An update over 1 million is not lackluster, no matter what the circumstance.
But guys, Blow me peak on iTunes was at #4 too, believe it or not. And when all the AI, sales based on performances she did, and timing matched, she went #6 on the BB 100. We are even waiting for her to crack the top 5 this week, and it is hitting #1 today on pop radio. My point is, i'd never expected it for that song, and iTunes position is the last relevant thing, if the song has a natural flow. Just a little patience.
