I don't think "La Raza" members would believe you on this. I know a lot of Hispanics who don't speak Spanish --- so I don't think it's language, plus many are atheists and Protestants so it's not religion and to me Mexican corridas and mariachis don't sound much like Puerto Rican salsas or Colombian cumbias and none sound like Julio Iglesias.
Of course, there are always exception to any rule.
