Before pursuing a solo career, she wrote songs for other musicians, including Joaquín Sabina, Miguel Ríos, and María Dolores Pradera.

The soundtrack for the 1996 movie Curdled featured her songs "Lunas Rotas" and "El Talismán", exposing her to an international audience.

Her second album, Luna Nueva, was released in 1998 and had a more mature and deep sound, but maintained the natural and smooth sentiments that characterize the artist.

In December 2003, Rosana released Marca Registrada, a double-disc album that contained 10 new songs, 12 greatest hits, and two videos.

In the summer of 2005 the album Magia was released and at Christmas time came Grandes Exitos, another greatest hits compilation.
