This one is not a Christmas song but I still feel that in the spirit of the season it fits well here. Since I've lived in Madrid, Spain I especially enjoyed this one. It's wintertime and the setting is the unemployment office. People in there are usually worried and down. Of course they are there because they are hopeful that they can either be placed in a job quickly or that they will be given some hope until they finally do. What better place than there to bring some magic and uplifting encouragement for a brighter tomorrow?
I love the humor of them showing the sign on the office saying, "Se Ruega Silencio." A rather flowery verb meaning, "It is begged of thee to maintain silence."
Because they are about to totally ignore the sign. haha
