JURO QUE ME DOLIO is Luck Ra admitting a breakup hurt, and promising to act like it didn't. The title says it all: "Juro que me dolió" (I swear it hurt), "pero haré que no" (but I'll act like it didn't), "porque por culpa tuya tengo roto el corazón" (because thanks to you my heart is broken). The opening is sweetly bitter. He'd like to dedicate this song to her so that whenever he hears it, he only remembers her, and he wants a single bed, "cama de una sola plaza", because "sobra la mitad si no estás en casa" (half of it is spare if you're not home).
The second verse gets sharper and funnier. "Sabes hacer muchas cosas, pero no amar" (you know how to do lots of things, but not love). Then the best line in the song: "Nunca voy a aplaudirte por serme leal, no voy a festejar que un pez sepa nadar" (I'll never applaud you for being loyal to me, I won't celebrate a fish knowing how to swim). In other words, loyalty is the bare minimum. He also realises he was so busy loving her "que me olvidé que me tengo que amar a mí" (that I forgot I have to love myself). The cheating is spelled out with a neat phrase: "metes a tres en cuento de a dos", putting three people into a story meant for two.
