I'm not sure if it makes sense, but I imagine she'd want to keep the impact of "listening to everything all at once" to boost hype, instead of dropping a single. It's like... everyone already knows what it sounds like, there's no need to try to present singles to sell it blindfolded like a normal album. But then letting people overflow with nostalgia on "first play" of something they already knew but sounds ~new? get the streams, etc. The long rollout because of Vinyl is tiring though. It would have been easier to check a calm week, announce it, drop it and then ship stuff later. She'd hit #1 two times probably dd.
