"mi cancion no es del cielo, las estrellas, la luna,
porque a ti te la entrego, que no tienes ninguna,
mi cancion no es tan solo de quien pueda escucharla,
porque a veces el sordo lleva mas, para amarla,
por eso canto a quien no escucha, a quien no dejan escucharme, a quien ya nunca me escucho
a quien en su cotidiana lucha me da razones para amarle, a quien ya nadie le canto"
-Silvio Rodriguez

It is sort of a chirstmas song, he is singing to the people that are deaf and other people that is not so fortunate, he thinks that this people could apreciate more the song that all of us... because there is not a lot of people that care about it, (sort of like that), he is just making a difference.
