1) Broken clocks was released as a promo single.
2) You're opinion of what the strongest songs on the album are, isn't necessarily the case.
3) The Weekend has already been released as a single, but SZA and solange have coordinate their schedules so they can begin filming
4) Doves in the Wind is still a fan-favourite
5) Shooting a video doesn't necessarily mean it will be a single (e.g. Supermodel was not a single and still had a video).
