This conjures up a quote from one of the greatest movies of all time from the great Burt Reynolds, who has unfortunately passed away.
Sally Fields was asking if he knew who these various singers were, he didn't and he told her some names and asked if she knew them, she didn't.
Then he said; "When you tell somebody somethin', it depends on what part of the country you're standin' in... as to just how dumb you are.” Burt Reynolds - Bandit.
While this may not apply exactly to what you are saying I would add that if you are given the opportunity to travel, see other places, meet other people, you are going to be exposed to a lot more. Being exposed to all of that is going to provide you experiences and that can give you that world traveled global intelligence.
If you live you whole life in one place and never travel you are never going to experience any of that and won't gain from that knowledge.
And if it matters I would say that yes my esoteric tastes in audio translates into other areas in my life.
