There have been "folk/world music" programmes on BBC Radio 3 in recent years, and what we might broadly regard as folk music does work its way into the classical pot-pourri-style programmes such as Essential Classics and the early evening In Tune Mixtape. It feels like integration, for which there's much to be said, as opposed to the segregation of separate folk music programmes. I use the word "segregation" deliberately tendentiously. The Beeb has been doing the same thing with jazz.
