Tell a story of any kind to one person and wait even 1 year and see how much the story has changed. There are IMHO no "set" "traditions "that arn't altered in some way through time.
To believe that "traditional" music began exactly as modern times i.e the advent of written or recorded music and hasn't been altered form it's point of origin is silly.
So enjoy what you like and play with passion and conviction to the relevance of the subject of the song.
that IMHO is the only way to be true to "tradition".
