Jinete translates to "jockey" or "rider". This word is the secret to understanding the song's title and its powerful final line.
"Vuelve Candy B" was the name of a legendary champion racehorse from Puerto Rico. By ending the song with, "Soy 'Vuelve Candy B', pero sin jinete" (I'm 'Vuelve Candy B', but without a jockey), Bad Bunny is comparing himself to an unstoppable winner who runs his own race, completely in control of his own destiny.
Bad Bunny is in full brag mode here, and honestly, it is hilarious. He kicks things off comparing his value to an expensive French Bulldog: "yo soy como un frenchie" [I am like a Frenchie], insisting he buys luxury Givenchy and Dior bags for girls instead of cheap Hershey chocolate. He chants "estoy burlao'" [I'm laughing my head off / mocking everyone], claiming he has dominated the peak for five years parked inside the paint like NBA legend Tim Duncan ("posteao'" [posted up]). He drops cultural references left and right, calling Lionel Messi the true GOAT in America over Tom Brady, throwing out old Air Jordan "Bred" sneakers for his own Adidas collabs, and comparing his dominance on the basketball court to legendary Puerto Rican shooter Eddie Casiano draining shots before Steph Curry was even around. The song's title itself references Candy B, a famous Puerto Rican thoroughbred racehorse, though Benito declares he runs alone: "Soy 'Vuelve Candy B', pero sin jinete" [I am 'Vuelve Candy B', but without a jockey].
Yet right in the middle of talking about nine-figure checks and buying real estate instead of jewelry ("comprando building"), he casually drops a cold reality check: "Me siento solo a veces, no tengo a nadie al lado" [I feel alone sometimes, I have no one by my side]. That brief admission makes the flexes hit harder. He reminds everyone that before the blue G-Wagons, sushi, and wine, people wondered who he even was. Now, while fake tough guys turn out to be chotas (snitches), he keeps the same inner circle from day one, shouts out his friends, and laughs at industry rivals by flexing both his Grammys and his Billboard records. It is cocky, funny, intensely Puerto Rican, and packed with everyday island slang you will want to rewind.
