In medieval times a ballad was a storytelling song, that's where the name comes from. I think that RsoW definitely IS a ballad, because it matches the two main characteristics of a ballad (as they are in my eyes): It is a slow but powerful Rocksong and it tells a story. Other examples are Bed of Roses, I'll be there for you, Never say goodbye, These Days ... ah yeah, talking bout ballads: November Rain
