Artillería literally means 'artillery', as in military weapons. It's a very striking and uncommon word to find in a song about heartbreak.
In this powerful lyric, Silvana Estrada uses it as a metaphor for her emotional defenses. When she sings "Abandonar mi artillería" (Abandon my artillery), she's declaring her intention to let go of her anger, her pride, and all the emotional 'weapons' she used in the relationship. It's a beautiful image of choosing peace and vulnerability in order to heal.
This song is a powerful anthem for anyone who has ever had to teach themselves how to move on. Silvana Estrada isn't just sad about a breakup; she's making a firm decision. The title itself, "Sabré Olvidar" (I will know how to forget), is repeated like a promise she's making to herself. She admits the pain is real, saying she carries misfortune between her teeth ("cargo la desgracia entre mis dientes"), but she has a plan: smiling, which she calls a remedy for the brave ("un remedio de valientes").
Her main tool for healing is her own voice. She believes the act of singing will make the pain vanish in her throat ("se ha de esfumar en mi garganta"). She also lays out a clear strategy: she will be quiet for a few days, abandon her weapons ("abandonar mi artillería"), and embrace the horizon. The song ends with a complex wish for her ex, hoping someone steals their heart without warning ("que te robe el corazón sin avisar") so that they can finally understand the intensity of what she felt.
