How to edit a run and gun music video?

I usually shoot to edit and have a lot of preproduction by the time I get into post-production. I just shot a music video though that was run and gun with zero preproduction and no idea of what the edit is going to look like. I just sat down to edit the video and hit writer's block. What do you guys do when you don't shoot to edit and justice have to come up with and edit in post-production? Or in other words, how do you guys edit a run and gun music video?
