A lot of folks have mentioned jazz as a music that we play at work. I wonder if it's more instrumental music without the distraction of words, or being able to work while your creative brain is multi-tasking, zoning on the organized chaos of the music and our respective workloads.
Perhaps that's a future and separate topic, altogether. :-p
