Ariana's team is so slow with music videos and they really need to act fast, but I don't trust them.
The only way to justify them being slow is if Ari performs at the BBMAs. She'll be pushed to #1 if she does.
Then they release the video the week after the awards and it allows her to remain at #1 for a while. Then by that time radio will have amped up their support enough that she can stay at #1 with no further promo.
But something tells me they aren't smart enough. Hope I'm proved wrong.
