During the past 18 years, the Norteña music genre has expanded from its homeland in the north of Mexico to the rest of the country. Even in places in the south of the country like Acapulco where so-called “Tropical” music such as salsa and cumbia still predominates you can find radio stations devoted to norteñas.
I’ve heard that it has even become popular in some parts of Brazil (could somebody confirm if that’s true?).
