People seem to consider their own little group "the world."
Like Dave, I may have heard some of these songs but I never paid any attention to them at the time.
A 'rolling stone gathers no moss' I remember from childhood. Dylan's song doesn't seem to have been good enough to make the Mudcat DT.

How many people outside of North America and Europe heard these songs? How many people IN North America and Europe heard these songs?

To reiterate my earlier comment, a silly poll with meaningless results.
