The band from Oviedo is currently number 3 among the top ten candidates. They are the only non-American band in the final stage, and you can vote for them here before 19 April, when the mission will start. You can also visit the band's official website (in Spanish) for more information.
I have posted the video of the song so that you can enjoy it. I hope you like it :-)
