n 1999, Lydia was selected by RTVE to represent the Spanish broadcaster in the Eurovision Song Contest, held on the 29th of May in Jerusalem, with the song "No quiero escuchar" (I Don't Want to Listen).
This was the 800th performance in the history of the competition. Lydia was very unlucky and finished last, receiving a single point from Croatia. In Spain there was widespread criticism of the dress she wore (by Ágatha Ruiz de la Prada) which did not suit with the style of the song. Some media tried to blame that fact for Spain's one of the poorest positions. The dress won the Barbara Dex Award for the worst of the year.
Unlike other artists who were unlucky at the festival, in 2004 Lydia stated on TVE: "At the end of the day, whether they like it or not, in 1999 I went to Eurovision, and that's something I'll be proud of all my life."
The song is a very underrated ballad and was widely played on Spanish radio in the weeks leading up to the competition, as well as on numerous TV programs such as ‘Música sí’ and ‘Sorpresa Sorpresa’. The videoclip was recorded in Barcelona.
