Agujeros translates to "holes". While seemingly simple, its use in this song is quite poignant and metaphorical.
Rels B sings, "En mi pecho hay agujeros" (In my chest there are holes). This isn't literal; he's expressing a deep emotional void or pain, likely from past betrayals or heartbreaks. It's a powerful image that conveys vulnerability and a sense of being incomplete, making it a memorable and emotionally resonant word in the context of the lyrics.
Rels B's "QUÉDATE, TE QUIERO" feels like a raw, honest look into his world. He starts by reflecting on past betrayals, saying "No sé cuántos me fallaron" [I don't know how many failed me] and how things have changed so much he's not even sure if he loves himself anymore: "Ya no sé ni si me quiero" [Now I don't even know if I love myself].
But even with that heavy start, he quickly shifts to loyalty and love for his close circle, promising "Mucho amor pa' mis hermanos Juro que os regalo el cielo" [Lots of love for my brothers I swear I'll give you heaven]. He's also got a special someone he wants to keep close, pleading "Mami quédate, te quiero" [Mami, stay, I love you]. It's a mix of street life imagery, with "En la mesa un par de gramos" [On the table a couple of grams], and a sense of being misunderstood, as he insists "Yo no soy el que ha cambiado, nah Solo quieren el dinero" [I'm not the one who has changed, nah They just want the money]. He's got big plans, though, with "Tengo todo planeado" [I have everything planned], and he's ready to share his journey: "Sube mami, yo te llevo" [Get in mami, I'll take you].
