Hello all,
Thanks A.T. for this topic, so very promising so far!
Personally, I'm a big radio lover, although I listen exclusively online these days. Ages ago as a teenager, I used to spend long days and nights listening to short wave radio from all over the world, it was more than just a hobby. Internet makes things easier though, and sound quality has improved a lot.
Anyway, sorry for the deviation. I'm a big lover of public radio, as you might have guessed, both for the quality of the programmes, and for the absence of publicity of any kind. To mention only a few of my big favourites: BBC (mainly Radio 3, Radio 4, 4 Extra and World Service), Radio France (most of the time it's either Culture or Musique, rarely Inter), RFI, RNE, SRR andCRo. I'm multi-lingual so these might not be suitable for everybody. There is a very good website for those who like the same things as me, it's PublicRadioFan.com.
As for music, I've got a subscription to a network called Digitally Imported, my favourite being JazzRadio.com and ClassicalRadio.com. Not free it's true, but I can't stand advertising and I think they are really good at what they are doing.
So sorry for the long post, I hope some of these thoughts will be useful to some. Happy listening!
