I concur with Brian.

But part of the whole problem (if that's what it is) is that "Traditional" doesn't mean "traditional."

"The Star Spangled Banner" is "traditional" in the everyday sense: it's been around a long, long time, and people still sing it, especially on certain occasions (as before major-league baseball games).

But capital-T "Traditional" means having some age, but it also means having notable variations in text and/or tune, and no recognized standard version.

A folkie chestnut like "Tom Dooley," of course, can be both. In one sense, the song was traditional because it had a long, if geographically limited, existence in various versions with no "standardized" text or tune. Once it became a copyrighted revival hit, text, tune, and timing (and to some extent instrumentation: who plays it on the piano?)became essentially frozen. Those who know the song see any variations in performance as mere variations from a well-established norm. The copyrighted "Tom Dooley" is "Traditional" only by special pleading, even if it has "Traditional" roots.

One-word labels with no context or elaboration are notoriously misleading.
