Brujería literally translates to "witchcraft" or "sorcery." It's a captivating and somewhat dramatic word that immediately grabs attention.
In the context of the song, the singer is sarcastically addressing someone who claims that her irresistible charm and the inability to forget her must be due to "brujería." She's playfully mocking their excuse, implying that her allure is simply natural and undeniable, not the result of any magic spell.
Yuridia's "Brujería" is a sassy, confident take on a breakup where one person just can't get over the other! The singer is basically calling out an ex who's going around saying it's "brujería" [witchcraft] that they can't forget her. She's like, "Tenga poquitos la verdad diga / Que otra de esas no se la pudo encontrar" [Tell a little bit of the truth / That you couldn't find another one like that]. It's pretty clear she knows exactly why he's struggling.
She playfully dismisses his claims of witchcraft, asking "¿Cuál brujería? ¿Cuál brujería?" [What witchcraft? What witchcraft?]. She knows it's not magic, but simply that he's missing all the good things she used to do for him: "Así le dices ahora a las cositas que te hacía" [That's what you call the little things I used to do for you now]. The singer is totally aware of her impact, even hearing through the grapevine that he's having trouble sleeping because he's thinking about her. She even warns him, "Va a estar cabrón pa' superar lo que ya tenías" [It's going to be hard to get over what you had]. Talk about a mic drop!
