"Caile" is a love song that sounds like a dance-floor invitation. The hook is pure slang: "Dale, ven y caile" (come on, come over here). Caerle literally means "to fall on" someone, but in casual Spanish caile is how you tell someone to show up or swing by. And he wants her there for one reason: "para que me baile" (so she dances for me).
He is completely lost in her, "Perdido en los lunares de tu cuerpo" (lost in the freckles of your body), and he describes her as a "Niña caprichosa, piel morena y de pelo negro" (a headstrong girl, brown skin and black hair). Under the party beat, though, this is a long-term thing. They have been "Juntos desde el instituto" (together since high school), he says "Como tú no hay dos" (there's no one else like you), and he even jumps ahead with "En el futuro seremos tres" (in the future there'll be three of us), which is a sweet way of talking about a baby.
The verses are full of easy imperatives worth stealing: "Bésame, quiéreme" (kiss me, love me) and "Ámame" (love me). He also admits "No somos perfectos, tampoco cualquiera" (we're not perfect, but we're not just anybody either), which is the most honest line in the song. The ending swerves into hustle talk, "Tengo que hacer dinero" (I have to make money), as if he needs to remind everyone he still has work to do.
