... or the skill of the audio techInteresting that you should mention that. Because that's what I'm talking about.
Sea shanties (note the root word - chant) are originally work songs They are designed to help a group of people who must act in unison do so. The Wellerman isn't exactly a classic chanty, but it is close enough to that root to have similar structure. The song is BUILT to have a group of people able to execute it together with ease. That's its actual purpose, its raison d'être.
The same is true for folk music, which, when combined with the blues, gets us country music. This is music designed for anyone with a fiddle or a banjo or guitar to sit down, and have the entire room signing.
A great deal of pop (and hip-hop) is designed to showcase the skill of the lead vocalist. There's good cultural and business reasons for that, but one result is that, broadly speaking, the genres become difficult for J. Q. Public to follow along with respectably, because they don't have that skill.
And I submit that's why the shared musical phenomenon was a shanty, and not a tune by the big pop stars of today.

And with respect to Sea Shanties, as with Marching Cadence, the chorus is the unifying factor. You don't need to know the other words. Hell, you can make them up on the fly like with a Rap Battle, but the chorus must be known. (Former resident of Nova Scotia, born in New Brunswick
