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.
This song from Argentinian artist MILO J is a super sweet declaration of love for someone who is perfectly imperfect. The singer is completely head-over-heels, describing how his world changed with just a smile. He sees his lover's face in the stars and feels like he's not good enough for her. But then he realizes something important: it's her flaws that he loves the most. He sings, "Con vos entendí que nadie es perfecto / Por tu carencias de cordura" (With you I understood that nobody is perfect / Because of your lack of sanity).
He doesn't just accept her quirks; he adores them. The song says her defects are exactly what make her so endearing: "son tus mismos defectos / Que te hacen ser una ternura" (it's your same flaws / that make you a sweetheart). It's a beautiful idea that true love means loving every part of a person, especially the 'crazy' bits. The song mixes this sweetness with a hint of danger, mentioning that on the night they met, he also "conocí el diablo" (met the devil), who was laughing and dancing. It suggests their connection is not just sweet, but also exciting and maybe a little wild.
