The authors of all the songs are ESDM - El Sueño De Morfeo themselves: David Feito, Raquel del Rosario and Juan Suárez.
The catchy Atrévete inherits the optimistic spirit of some of the early successes of the group introducing new sounds like the banjo. Contigo Hasta El Final is a musical journey of emotions going from an epic introduction to a rockier theme that evoques a romantic intimate scenery. The band describe Dame Tu Voz as "a call for unity, to unite our voices and bring a message of hope, especially considering the times.
In these times we need hope. Where there's a will there's a way and together we will succeed
The winning song will be chosen by a 50/50 mixture of televoting and a jury vote. The jury consists of journalist José María Iñigo who is the Eurovision commentator for Spain, singer Rosa Lopez who represented Spain in Tallin in 2002 with the unforgettable song Europe's Living A Celebration and this year's Italian Eurovision act, Sanremo 2013 winner Marco Mengoni.
In addition to perform the three participating songs, ESDM - El Sueño De Morfeo will share the stage to duet with last year's Spanish performer Pastora Soler, singer Alex Ubago, the band La Musicalité, and the Italian artist Nek.
