Aprueba de balas literally translates to "bulletproof". It's a striking and powerful phrase that immediately grabs attention, suggesting resilience and invincibility.
In the song, Sebastián Yatra sings, "Que yo te presto mis alas / Que son aprueba de balas" (I'll lend you my wings / That are bulletproof). He uses this vivid metaphor to express his unwavering support and protection for his loved one, promising to shield them from any harm or fear. This unique imagery makes it a truly memorable and enticing phrase.
“En Guerra” paints a vivid picture of someone silently battling self-doubt. From the outside, everything seems calm, yet inside there is a storm that only the singer can sense. Instead of judging, he offers unconditional support: he wants to hunt down every fear, erase all sadness, and lend bullet-proof wings so his loved one can fly free. The recurring question “¿Qué le pasará a tu espejo?” shows his frustration that the mirror cannot reflect what he sees—a person already perfect, already all he has ever wanted.
The chorus flips the usual love-song script. Rather than asking the other person to change, Yatra and Camilo confess they want to be more like their partner. Her laughter brightens stars, her kisses set the whole planet spinning, and her innocence fills their world with light. “En Guerra” is ultimately a warm anthem of reassurance: when you feel at war with yourself, remember that someone out there sees your true brilliance and is ready to stand beside you—under the battle skies and beneath the stars of love.
