Brujería translates to "witchcraft" or "sorcery". It's a captivating and somewhat mystical word that stands out from typical song vocabulary, making it memorable and intriguing.
In the song, Mora uses it metaphorically to describe the powerful, almost magical hold his love interest has over him. He sings, "Brujería, mami, tú me hiciste brujería" (Witchcraft, mami, you put a spell on me), implying her irresistible charm and influence are like a spell he can't break.
This song is one big, desperate late-night text to an ex. Mora kicks things off by admitting that everything reminds him of her, from beautiful memories in a hotel suite to a crazy night on a balcony in Italy. He's so stuck on her that he wishes he could meet her all over again, just to fix whatever went wrong. He's very specific, though: he'd change some things, but definitely not the physical side of their relationship, saying he'd change things "menos esos polvos" [except for that sex].
The chorus is where the real drama unfolds. He tells her, "Ma, yo no te di mi corazón / Eso fue un robo" [Ma, I didn't give you my heart / That was a robbery]. He feels like she stole it from him. He's so consumed by the breakup that he says the only way to forget her kisses is with drugs: "pa olvidar tus besos se necesita droga" [to forget your kisses, you need drugs]. It's a super intense way to describe how addicted he is to her memory, showing she's both the one who makes him lose control and the only one who can calm him down just by saying hello.
