Born on May 23, 1974, in Figueres, Catalonia, Spain, Naranjo made her recording debut at a young age, releasing Monica Naranjo in 1994 on Sony. Produced by Cristóbal Sansano, the self-titled album proved popular in Latin America as well as Europe, spawning a series of hit singles including "El Amor Coloca," "Sola," and "Sólo Se Vive una Vez." The follow-up album Palabra de Mujer (1997) was an even greater success, particularly in Spain. Again produced by Cristóbal Sansano, Palabra de Mujer spawned another round of hit singles including "Desátame," "Pantera en Libertad," "Las Campanas del Amor," and "Entender el Amor."

Naranjo's third album, Minage (2000), marked a change in her career trajectory. Following two multi-million-selling international smash hit albums, the singer/songwriter released a decidedly uncommercial album, a full-fledged tribute to Italian diva Mina Mazzini. While her record label wasn't especially pleased with her decision to release such an album, just as some of her fans weren't thrilled with her turn away from commercial pop, Minage still sold over a million copies worldwide, spawned a few hits, most notably "Sobreviviré," and remains a favorite of many fans.

In contrast to Minage, Chicas Malas (2001), Naranjo's fourth album, is a dance-pop album through and through. Her most collaborative effort to date, it includes the singles "Chicas Malas," "Sacrificio," "No Voy a Llorar," and "Ain't Better Like This." An English-language version, Bad Girls, was released in 2003. After a couple more years, Colección Privada (2005), a greatest-hits collection featuring a new single, "Enamorada de Ti," was released. Not until 2008, a long seven years since Chicas Malas, her last album of all-original material, did Naranjo release her next album, Tarántula. Led by the smash hit comeback single "Europa," Tarántula was an all-around success, topping the Spanish charts and garnering acclaim from fans as well as critics.
