I work in an office of a large engineering company, and talk to agents and customers on the phone both in the UK and worldwide, so it would be very un-professional to listen to the radio.
I therefore tune into Chris
Evans on R2 for his breakfast show, then listen to my iPod (The Clash, Green Day, Saxon etc) till about lunch time, then switch to Kerrang Radio and Punk Radio (Duisburg, Germany) for the rest of the afternoon.
