The Spanish participating broadcaster, Radiotelevisión Española (RTVE), organised the national final Misión Eurovisión in order to select its entry for the contest.

Five acts and five songs ultimately qualified to compete in the televised final where a public televote first selected the top five to advance to the second round.

In the second round of voting, a regional televote exclusively selected "I Love You Mi Vida" performed by Nash as the winner.

It has also finished second four times, with "En un mundo nuevo" by Karina in 1971, "Eres tú" by Mocedades in 1973, "Su canción" by Betty Missiego in 1979, and "Vuelve conmigo" by Anabel Conde in 1995.

After a restructuring that led to the incorporation of TVE into the current Radiotelevisión Española (RTVE) corporation on 1 January 2007, it was the latter who participated in the 2007 contest.

For its 2007 entry, RTVE announced on 2 November 2007 that it would organise a national final featuring a competition among several artists and songs.

[3] Misión Eurovisión was the national final organised by RTVE that took place at Prado del Rey in Pozuelo de Alarcón (Madrid), hosted by Paula Vázquez.

For the regional televote, the votes of each of the nineteen autonomous communities of Spain created an overall ranking from which a set of points was distributed.

[10] Two separate submission periods were open on 14 November 2006 for artists and songwriters to submit their applications and songs.

At the show, the five songs were performed by five established guest artists in the following order: The final took place on 24 February 2007.

In the superfinal, the winner, "I Love You Mi Vida" performed by Nash, was selected exclusively by regional televoting.

[28][29] On 21 March 2007, it was announced that Nash would perform at the Eurovision Song Contest under the name D'Nash due to issues with registering their initial stage name.

[30] According to Eurovision rules, all nations with the exceptions of the host country, the "Big Four" (France, Germany, Spain and the United Kingdom) and the ten highest placed finishers in the 2006 contest are required to qualify from the semi-final in order to compete for the final; the top ten countries from the semi-final progress to the final.

The Spanish performance featured the members of D'Nash on stage dressed in white outfits and doing a dance routine, joined by two backing vocalists on silver kettle drums.

The LED screens displayed a digital mosaic background which transitioned between blue and red colours, with the latter covered by the title of the song "I Love U Mi Vida".
