Most of what passes for radio in Orange County gets broadcast from Los Angeles or Burbank studios, and even our one big station, the Fish, seeks a Southern California audience, so it's refreshing that this Spanish-language station is puro naranjero, from the ads to the jokes to the promotions. It's so Orange County that it targets one specific demographic: chilangos, people from Mexico City. The music played is what you'd expect to hear in the capital, a heady mix of cumbias, salsa, the occasional quebradita and reams of sonidero. And Saturdays turn into "Sábados Distrito Federal," the "Saturday Night Safety Dance" of SanTana.
