Speaking for the traditional folk songs: Funny thing. Once upon a time I may have wished not to hear again, say, Red River Valley or Blue Tail Fly, I find all I have to do is live another year or two and I begin to hear those old songs' inner beauty, sometimes in different terms than before.

So, me personally, I would hesitate to name any traditional song that I wouldn't like to hear over again, maybe after a little time's gone by. And so to remove any doubt I hasten to say I love the above two songs, Red River Valley and Blue Tail Fly, and pretty much all the rest, because they keep surprising me and revealing themselves to me little by little.

So it's a matter of perception.

About the other songs called "folk," contemporary folk and so on, I'm not sure I can say anything useful.
