I love the radio and have it on in the background most of the time now.
I tend to listen to Radio 2 during the day although I do often have to turn it off when Jeremy Vine comes on as I end up shouting at the radio.
I also use iplayer to listen to lots of dramas and things on Radio 4. I tend to listen to Womans Hour, Book of the Week, Play of the day/week, The News Quiz, The Archers, Gardeners Question Time and Kitchen Confidential. I download quite a few of them as podcasts and listen to them at night.
I also download Simon Mayo's confessions and Chris Evans breakfast show (best bits) on a weekly basis.
I never listen to local radio as it drives me insane. The only time I might turn it on is in the winter for the local weather reports and school closures.
