I never got on with radio 3
I like classical music, but not all of it. I am very mainstream I guess. I like Mozart, Bach, Beethoven, Vivaldi, Verdi, Puccini, Bellini, Schubert, Schumann, Prokofiev, Tchaikovski...the usual suspects, but can't enjoy Bartok or Shostakovitch or anything "modern-classical" or anything a-tonal. I am listing all this to show I like a lot of classical music, but am not keen on radio 3. there must be more low-brow people like me.
Saying that, I don't like it when they only play the adagio's of concerts, I would prefer an entire symphony/violin/piano-concerto.
Classic FM is a bit cheesy, and I hate the banal listener comments, but it is quite good in the car.
Radio 3....I have never listened to it long enough to discover new music on it. I discover new pieces on Spotify or at concerts.
Good luck anyway, it's a shame if something is downgraded.
But I imagine their listener base must be quite small? And they try to grow?
