Interesting credit on the song playing when you open Tom's site.

I'm not clear precisely what on his site is deemed a "smart approach" - but if it's offering a choice of a singer-songwriter set or a folk set, I think Travelling Charles Fyson used to dotaht, and indeed go one stage further by offering US folk/county or English folk as options as well as singer-songwriter.

So maybe it's a trad of folk solution to the problem.
