Spain participated in the Eurovision Song Contest 2003 with an entry selected through the second series of the reality-show Operación Triunfo, hosted from Barcelona by Carlos Lozano. Beth with the song "Dime", composed by Jesús María Pérez and Amaya Martínez, was chosen through televoting by the Spanish public. At Eurovision, Beth placed 8th with 81 points.
After the regular final of Operación Triunfo (where Ainhoa Cantalapiedra was declared the overall winner), the top 3 contestants - Ainhoa herself, Manuel Carrasco, and Beth - qualified for the Eurovision phase of the contest, which consisted of a semi-final and a final. Three songs were assigned to each contestant among those submitted to national broadcaster TVE, making a total of nine songs. In the semi-final, a jury eliminated one of the songs assigned to each artist, and then a finalist song was chosen for each contestant through televoting. The three songs that participated in the final were "Mi razón de vivir" by Ainhoa, "Viviré, moriré" by Manuel Carrasco, and "Dime" by Beth.
