Presas literally means 'trapped' or 'imprisoned'. It's a powerful, evocative word that paints a strong picture.
In the song, KAROL G uses it metaphorically, singing "están presas en mi corazón" (they are trapped in my heart) to describe how her overwhelming feelings leave her speechless. This poetic usage captures the feeling of being unable to express yourself when emotions are too intense.
Have you ever missed someone so much it feels like your whole world stops? That's the feeling at the heart of this track from Colombian superstar KAROL G. She's completely fixated on one person, telling them, "No quiero vida si no es contigo" (I don't want a life if it's not with you). It's an intense declaration! She spends her days remembering holding their hand and feels like her life is slipping away just thinking about them.
She's also getting zero response, which makes it all the more desperate. She sings about making "Par de llamadas al celular y tú no me contestas" (A couple of calls to your cell and you don't answer) and sending messages with no reply. It's a classic case of being left on read! She's stuck with a "foto mental no la puedo borrar" (mental picture I can't erase) and is left wondering what this person did to her that she just can't let go.
