You'd think, though, that third and fourth generations would be like the third and fourth generations of other ethnicities and embrace other musical genres. Plenty of rock fans are Italian-American, Irish-American, Greek-American, Russian-American, Japanese-American, Chinese-American. They're not all listening exclusively to music produced in, or in the styles of, their great-grandparents' homeland. The old jigs and horas and whatever other ethnic dance music forms are only dragged out at weddings that great-grandma and her friends are present for. Why should Americans with roots in Latin American countries or Puerto Rico be different? Are their brains hard-wired to respond only to Latino rhythms and lyrics, no matter how long ago their family actually lived in Latin America? That can't be, because that would be a racist theory, right? So what's the answer, David? Not enough third- and fourth-generation Hispanics in the population yet?
