Carencias means "lacks" or "shortages," and cordura means "sanity." The full phrase carencias de cordura is a beautifully poetic way of saying someone has a touch of lovable craziness or unconventional thinking.
In the song, MILO J uses this phrase not as a criticism, but as a term of endearment. He sings that he loves his partner because of her "lacks of sanity," celebrating her unique quirks and imperfections as the very things that make her so endearing and perfect for him.
Argentine rapper MILO J teams up with Yami Safdie for a sweet, slightly wild love song that ditches the idea of finding a flawless partner. Right away, the lyrics set up a crush so intense it knocks the wind out of you: "Contento, y sin aliento, miré hacia arriba" ("Happy, and breathless, I looked up"). Looking at the full moon, the speaker sees their crush's face in a star and admits feeling completely outmatched by how pretty she is ("Sentí yo no estar a la altura" ["I felt I wasn't up to standard"]). But the real heart of the track is embracing the chaotic side of love.
The title says it all: "carencias de cordura" translates to "lacks of sanity." Instead of running away from someone's quirky or unstable habits, the chorus welcomes them warmly: "Con vos entendí que nadie es perfecto / Por tu carencias de cordura / Pero es que son tus mismos defectos / Que te hacen ser una ternura" ("With you I understood that nobody is perfect / Because of your lack of sanity / But it's your very flaws / That make you so sweet"). There is also a playful, mischievous energy when things heat up—the lyrics mention meeting the devil on the dance floor ("El diablo reía, el diablo bailaba" ["The devil was laughing, the devil was dancing"]). It is an honest rap track about falling hard for someone, messy habits and all.
