From the Maritime worksong thread:
Steve: I'm not interested in what modern day practitioners and commercial interests use it for. Its usage aboard merchant ships under certain conditions c1830 to c1920s is well documented and that's all I'm primarily interested in.

If you and your interest have an outlet, usage = marketplace = genre.

Systems Audit 101: Say as we do. Do as we say. If your marketplace is a standing watch or work detail - it's a worksong. If not, it's in a different genre, ie: forebitter or popular song. Adulteration comes with the territory.
