"I'd infer this considering the first line (Estrella de la manana) translates into "Morningstar" which is another name given to Satan or the Devil and "Samael" is also another name given to the Devil.

-Jonny"

Samael is rarely used as reference to satan, hes listed int eh same sphere of demons and etc there were kicked out of heaven but not satan himself. and in hebrew literature hes refered to as either the prince of demons, or the angel of death. not satan.
