The younger generation are exposed to many more types of music than the majority of the "oldies" in the folk clubs ever were, from a much wider media output.

They don't feel the need to limit their listening to one particular genre at the expense of others. They don't categorize their listening pleasure to such an extent that their ears are closed to anything new and refreshing.

Late Junction as mentioned above by a few, is an excellent show with a varied output, and high listener numbers. Maybe they ARE providing what people want.
