Vacía means "empty" or "hollow." It's a common word, but its repeated use in this song, especially in the phrase "me vacía" (it empties me), gives it a profound and central meaning.
The artist uses it to express a deep sense of emotional depletion and unfulfillment, despite being in a relationship. It highlights the feeling of being drained rather than filled by love, making it a poignant and memorable word in the context of the lyrics.
Have you ever been stuck in a cycle with someone, where it feels like you're constantly repeating the same arguments, the same goodbyes, and the same reconciliations? That's exactly what Gran Rah and Flor de Rap explore in "Vacío Lleno" [Empty Full].
They sing about the frustration of a relationship that's full of contradictions: "el mismo beso la misma negatividad" [the same kiss the same negativity], "el mismo vete lejos el mismo vuelve pronto" [the same go away the same come back soon]. It's a push and pull where they both admit to the pain, but also the deep connection. Gran Rah even says, "juré nunca más escribir desde su amor y mírame reescrito igual" [I swore never to write from her love again and look at me, I've rewritten it anyway]. It's a really honest look at how hard it is to let go, even when a love feels like it's leaving you empty instead of full.
