I'm pretty sure Taylor is plotting her revenge right now. She probably has already written 2 more albums since Hello was released and of course she's gonna pint it on Calvin Harris or some other penis that walked in on her at an award show.
Youtube Stats are not usually an accurate source for the first 24hs of release, so take it with a grain of salt. Either way, i'm not really sure what is VEVO waiting for to confirm the numbers!
