Yeah, it would be super difficult for Taylor to hit #1 on the Hot 100. Even if she gets 15 million US streams and 35m AI, she'd need like 500k sales to hit #1. Now of course she could outdo either of those with a miracle, but it's not going to be easy.
im pretty sure its at 11 cuz thats when all new releases come out, could be wrong though.
That's when new releases are, but the chart week rolls over an hour later. There's often lost sales in that period - 1989 for example lost a few hundred copies to that hour (it's usually a super small number). Bad Blood will probably lose a a few thousand with its early release.
