A conducive work environment...

...probably doesn't usually include "Tragedy" playing quite loudly outside your door. I love our secretary dearly, but she is rather overgenerous with sharing her music. And her tuneless whistling - which just started up as I typed that. Serves me right I expect.

However, I am so far from being focussed in any case that the difference is probably quite minimal...

And if I'm honest "Tragedy" is pretty fun... w00t!
