Folk music isn't a homogenous sort of thing. Its unusual to find someone who can listen to all sorts of folk music. Usually within an hour the DJ will play something that irritates you beyond measure.

Also in England, rather than proper DJs - skilled at putting together a varied and listenable show. The show tends to fall into the hands of some performer or other. So they play rubbish by someone or other they think will help them in their career - the dire residents at some club they think they might get a gig. Or the organisers of festivals.

I dunno what the answer is. It must be a difficult job. Everybody seems to put out cds these days. When it was just club pros doing recordings - nearly every track had worked for a place in an act, and it 'worked' with an audience. Nowadays there aren't really enough clubs for acts to assess how good a song is.

Still you have the 'preserve the tradition no matter how dreadful gang' to blame for that. thats what led to the mass closure of clubs in the 1970's.

Nowadays people seem to record just as soon as they can play a song. Regardless of whether anyone likes it.

commonsense tells you the DJ can't have listened to half the stuff they play (they wouldn't have time) - so I suppose that's why they play so much lacklustre stuff.
