Things were going pretty well for my project, but I had some work to do getting from there to the collaborative playlist I had in mind. I was already just assuming we were only caring about one file, because that worked well to get things up and running fast.

So, I set about this yesterday afternoon (when our Ship It festivities officially begin) and I had a vague idea where I wan...
