Patrocina means "sponsors" or "finances." It's an interesting word because it's not commonly found in everyday song lyrics, especially in this genre.
In the context of "El Quince," the lyrics state, "La empresa lo patrocina," implying that a powerful entity or organization is backing the protagonist's operations. This word hints at a larger, perhaps illicit, network or business, adding a layer of intrigue to the narrative of the song.
This song, "El Quince" by Abraham Vazquez, is all about a guy who's super loyal and ready for action. He's got his rifle, he's flying high, and he's always on the move. He talks about protecting his territory and how he's the "good one" who was given his position and will never fail.
He identifies himself by his key, "yo soy el 15" [I am the 15], and he's always working. He mentions that his family is everything to him, the reason for his success. He's a soldier, good at driving and piloting, and he's been through a lot with his friends, good times and bad, always ready to act. It sounds like a life of constant vigilance and loyalty to his crew and family.
