Folk song/music. 1954 definition.
Folksinger.   A singer of folk songs who has learned them through the folk process.
Folksong-singer. A singer of folksongs who has learned them in any other way.

So what does that distinction actually mean, in practice? Doesn't it sorta imply that "folksinger" should be reserved, at least for the most part, for blind singers who don't read braille?
