Well, both my father and my first husband were in the forces so I've lived in lots of countries......and tried to learn the language in each although cantonese was tricky and I only really learned to curse effectively in it.
When it eventually came to settling down I noticed that I had to be very careful not to start a sentence with " When I lived in such and such a place" as people automatically turned off either because they thought it was deliberate swank or that it would have no bearing on what they were interested in.
I learned that you don't have to travel to be broadminded..I met lots of narrow minded people in other countries as well as at home.
Can't comment as to whether I would do it again, it was my whole life and I can't imagine another.
As for music....well, I was exposed to lots of different kinds and enjoyed most....although the atonal chinese stuff never sounded comfortable to my ear.
