Having as much contact as possible with authentic real language is one of the key factors for learning. Years ago it was really difficult; English was not round the corner. That was only feasible if you were learning the language in the country where it was spoken or through satellite systems good enough to resist breakdowns and interferences. Fortunately things have changed so much that the issue is an entirely different matter. Digital radio, for instance, provide us with that possibility.
