Music in the workplace, pros and cons

From Mumsnet’s Justine Roberts column in the FT:

A recent meeting at a music tech giant was augmented by a lively soundtrack which (possibly as a result of my age) I would undoubtedly have found distracting had I worked there every day — both because I would find it difficult to concentrate with all that noise, and because I would be fiercely competitive about wangling my own playlist (dominated by Prince, naturally) on to the system.

On the other hand, a potentially infuriating 40-minute encounter at my bank last week was substantially improved by soothing piped jazz. I found myself humming along quite happily, and was far less bothered by the inertia and incompetence of the staff than I would have been had there been no sound other than the pinging of ATMs, punctuated by occasional interjections of “Computer says no”.

So which is it to be?
