I'd love to be able to listen to them at work but don't think I can concentrate enough on work whilst doing it. I sometimes just put my headphones on with nothing on, but that's just to tone down the general office drone when I have to focus on a particular task. It also has the benefit of putting people off asking questions and putting you off your stride.
When i'm off work in a week's time I may get a chance to catch up. I have 55 recordings outstanding.
