Encerraditos is the playful, diminutive form of encerrados, meaning 'locked up' or 'confined'.
In a highly memorable lyric, the artists sing about being "encerraditos como en dos mil veinte" (locked up like in 2020). They use the shared global memory of pandemic lockdowns as a clever, flirtatious metaphor for wanting to be completely isolated and alone with a crush.
This song is a super fun and direct invitation to someone the singers can't stop thinking about. Aitana kicks it off by admitting she's totally obsessed, singing, "No hice la tarea de olvidarte / Porque siempre fui mala estudiante" (I didn't do the homework of forgetting you / Because I was always a bad student). She's not even trying to get this person out of her head and spends her days imagining what it would be like to be with them. The chorus is a straight-up challenge: "Dime si me quieres / Si quieres algo conmigo" (Tell me if you want me / If you want something with me), basically telling the person to stop waiting around and be more daring.
Emilia and Ptazeta jump in and turn up the heat. Emilia gets creative with her compliments, comparing the person's body to a work of art she'd paint if she were Frida Kahlo. She makes it clear the feeling is mutual with lines like "Te doy la password pa' que tú te conectes a mi red" (I'll give you the password so you can connect to my network). Then Ptazeta promises a wild night, saying they'll lock themselves away "encerraditos como en dos mil veinte" (locked up like in 2020) and that "en esa cama nadie va a dormir" (in that bed, nobody is going to sleep). It's a bold, confident track about knowing what you want and asking for it.
