Bestias translates to "beasts" or "wild animals". It's a striking and somewhat unexpected word to find in a pop song, making it memorable and intriguing.
In the context of the song, the lyrics state, "Y se despertaron nuestras bestias" (And our beasts awoke). This suggests a metaphor for primal desires, passions, or perhaps even darker, untamed aspects of human nature that are unleashed when two people give in to their impulses. It adds a layer of intensity and raw emotion to the song's narrative.
"Bestias" starts with two people pretending this wasn't on purpose. "Accidentalmente nos dejamos llevar" ("Accidentally we let ourselves go"), David Otero sings, "Y se despertaron nuestras bestias" ("And our beasts woke up"). He knows he's acting strange around her and doesn't bother denying it, barefoot next to someone who has it together: "Yo voy descalzo y tú tan fresca" ("I go barefoot and you're so put-together").
The chorus turns her into weather and poetry at once. She makes him feel like "las mañanas de sol" (sunny mornings), like "los poemas de amor" (love poems), and "Lo que hace que te quiera tocar" ("What makes me want to touch you") is as plain as the song gets. By the bridge she's carrying "los rayos del sol" (the sun's rays) and "los secretos del mar" (the sea's secrets), more than one person should hold. It all comes down to one question, asked and answered: "¿Te acordaste tú de mí?" ("Did you remember me?") and "Me he acordado hoy de ti" ("I remembered you today").
