> it's like saying hungarian music is the same as portuguese or irish music since it' all european anyway
That's a bad analogy.
For starters the groups you listed have very different roots reaching back to ancient times and that still has it's mark on everything not just on music. Christianity washed away much, but these three groups had over a 1000 years of separate evolution too, which not just means very different historical background, but it led to different mentality and taste. While everything from South America is product of modernity. Roots from a generic amalgamation of Western Med, South American native and sub-Saharan African taste, and modern cultural trends which are the same everywhere on the globe is piled upon it.
Much better analogy would be the comparison of Hungarians and Northern Hungarians, which almost boils down to language difference. But that "almost" is still bigger divide than what Brazil and other South Am (and Mesoamerican and Caribbean for that matter) have between them. The best parallel would be Croats and Serbs. If you are in either, yeah for you it will be different (and it will matter for you), but for any outsider it would be the same.
I'm sorry but Brazil isn't any different than any other country from those parts.
