At work, when there's sport on, 5 Live Extra or the County Cricket commentaries via the BBC website;
BBC Devon via Player for the City commentaries;
Radio 5 Live (or Radio 4 LW via 720AM) in the car for sport;
Occasionally Absolute Radio.
Used to listen to 6 Music on my headphones at work before I worked in a small shared office, but stopped when Gideon Coe moved to a late show instead of daytime.
During the week 5Live in the morning before I leave, 6Music or occasionally 4Extra in the car and then 6Music during the day. Used to be that as soon as they played one weird track that someone else in the office would complain and switch on to Radio 2 (which, after 12 and before 5, leads me to get increasingly angry), however I've now moved into a different office and am free to have my own choice on.
Over the weekend it'll be a mix of 5Live, Phonic FM and either 590 The Fan or TSN1050 for ice hockey commentary on the rare occasions that I can't find a TV stream.
Start off with Radio 2 first thing these days until 9.30. Then I turn over to Radio 1 because I'm not a great lover of Ken Bruce until 11am and then it's Kiss for an hour. Back to Radio 1 until 1pm and then it's Radio 2 for the rest of the day. Unless it's a Saturday, and then it's 5 Live all day.
