Presentation has quite a bit to do with it. If a rock band or the Mormon Tabernacle Choir or Kathleen Ferrier sing a folk song, the presentation removes it from the "folk context" that SS loves so much, but it does not alter the fact that it's a folk song.

Would I make an effort to hear a program of folk songs done by a hard-rock band? Probably not, especially when there are other options available.
