Man, you guys are working in the wrong law firms! I've got the tunes cranked all day, every day, unless I'm having trouble concentrating (or on the phone with a client!). I've slowly been converting folks who stop by the office to the music by doling out the usual suspects--KOB, Blue Train, etc. Maybe I'm lucky!
I also work in a law firm and music, while not specifically forbidden in a written policy, would never be played here. A few people over the years have liked jazz, not many. One tried to convert others to jazz and was always met with awkward, embarassing silence and inappropriate comments.
One of the clients talks often of his love of Duke Ellington and this is often cited as evidence of his unbelievably weird nature by people who work here.
Best to keep it to yourself, in a law firm--and that applies not just to a love of jazz.
are you, by any chance, down the hall from me?!?
