There’s also the idea that Hard School has leaked. IF it’s the lead single reworked it could help bury that having happened. Yeah for us it sucks in ways for a single to be a song we have known. But for a great many it’s new to them. If a album is really in the works for release and they are using old material. It would make sense to lead with leaked material. Especially when a good majority have looked at the song as hit single material. Then they can keep the veil over anything that’s unheard currently by all. No sense spoiling the fraction of an album that’s unknown. Leave a little mystery.
