On a certain level, it seems to be why pop music is mostly 95% about love and offshoots/aspects thereof. Love, sex, and allied industries, being a main aspect of human life experiences on this planet, the Music Business concentrates on this LOVE topic for almost all of the product they create and sell to everyone world wide.

Traditional ballads and folk songs truly do reflect the manyaspects of topical life---geography, historical drama, narrative depth, etc.---not only love. Being a smallish niche at best, you can only SELL these songs to people who know what you are talking about. Geographically speaking, the western USA relates to, and sings about, cowboy lore. The ballads of lumbering areas in the 1800s tend to be reflective of the reality of lumberjack life. Near the shore of an ocean, the songs are of fishing/whaling adventures.

So, the collectors did seek out smaller folkloristic geo-pockets to find songs that were illustrative of specific song types;----i.e. the ARCHIVE OF FOLK SONG at the Library of Congress. That venerable old depository, over the years, has meant a whole lot to me and to others from the Folk Revival tears here. But the more things change, the more they get different; Alas, the Archive of Folk Song no longer exists. It has been replaced by The Archive of Folk Culture---an all inclusive magnet for the music, yes,---and also other ephemera-flotsam and jetsam that might more appropriately be housed at the Smithsonian's Museum of American History where Charlie McCarthy and Mortimer Snurd now are entombed.

But I digress. Sorry---but there it is,,.

Is this what you mean by Psychogeography and Folk?
