Polo González's "Comprobado" is a confident anthem about his success and resilience. He makes it clear that he's worked hard, saying "más esfuerzos que talento por haber el resultado" [more effort than talent to get the result]. He's not bothered by what others say, even when they compare him to others, because he's focused on his own journey and "sigo acumulando logros bien tranquilo" [I keep accumulating achievements, very calmly].
He's proud of how far he's come, noting that he's "ando recio pues el freno no he pisado" [going strong because I haven't hit the brakes]. It's a great feeling for him to achieve his dreams by being consistent. He also enjoys the finer things, like cruising in his truck with its "motor alterado y el sonido acción desmadre" [altered engine and the sound is a party]. The song ends with him still dreaming big, even as he enjoys a smoke, with "llenos de humo mis pulmones de mis sueños sean grandes" [my lungs full of smoke, may my dreams be big].
