She first rose to prominence as the lead singer of Pic-Nic, a teenage folk-pop band that found success in 1968 with her song "Cállate, niña".

Jeanette returned as a solo artist in 1971 with the Hispavox single "Soy rebelde", which redefined her career as a romantic balladist and was a hit across the Spanish-speaking world, becoming a generational anthem.

After the international success of "Porque te vas", Jeanette worked in France and Germany until she returned to the Spanish market with the 1981 album Corazón de poeta, which includes several of her most famous songs.

The commercial reception of Corazón de poeta allowed her to record two more albums with RCA Victor—Reluz in 1983 and Ojos en el sol in 1984—which were unsuccessful.

Her last studio album, Loca por la música, was released in 1989 on independent record label Twins and sought to reinvent her style with techno-pop influences.

[3] After her band, Pic-Nic split up at the end of the 1960s, Jeanette moved to Vienna with her husband, Hungarian football player László Kristof, and lived quietly as a homemaker and the mother of their only child, Blythe.

Later she joined the student band Pic-Nic as a singer, and in 1967 they had a measure of success with a folk version of the Spanish children's song "Cállate, niña" (in which Jeanette had co-written).

The single first enjoyed success in Spanish-speaking countries and later broadened its influence with French ("L'inconnu qui m'aimera"), Japanese ("あまのじゃく") and English versions.

Her greatest success, "Porque te vas" (Because you are leaving), written by José Luis Perales, became an international hit when the song was used in Carlos Saura's 1976 film Cría Cuervos (Raise Ravens).

[11] In the next several years she released the albums Reluz (1983), Ojos en el Sol (1984), and Loca por la Música (1989), along with a string of singles.
