Selena and her collaborator brother A.B. Quintanilla III grew up listening to classic pop, R&B, and disco, so it's no wonder those influences materialize on Entre a Mi Mundo. The Tejano queen's fourth album for the EMI Latin label is consistently satisfying and wonderfully diverse, from the rousing cumbia "La Carcacha" (about a boyfriend's beat-up old car) to the spirited mariachi kiss-off anthem "Que Creias," which has become a fan favorite. "Missing My Baby" is street-smart R&B, and "Amame" pulses with fiery club rhythms. Much of the credit should go to Quintanilla, who helped Selena challenge the often-stifling boundaries of Tejano music. Entre a Mi Mundo also includes Selena's first international hit, "Como la Flor," a lilting cumbia highlighted by a pleading vocal delivery and lost-love lyrics. --Joey Guerra
