I can't believe anyone can trumpet about internet radio, while also having a go at DAB for its sound quality.
Internet radio is great, but sound quality is not its forte. And then there's the lags and breaks in audio when the buffer runs dry.
Besides that, broadcasting to a large number of people over a well defined geographical area through the internet is madness. If you and your neighbour are listening to the same radio programme, you have two copies of exactly the same information being streamed down the same wires. It's a huge waste of bandwidth and resources.
