Lunares literally translates to "moles" or "beauty marks". It's a wonderfully specific and intimate word that you don't often hear in a love song, making it very memorable.
In one of the song's most famous lines, Shakira sings, "Yo puedo escalar los Andes sólo por ir a contar tus lunares" (I can climb the Andes just to go count your moles). This grand, romantic exaggeration (hyperbole) shows a deep level of intimacy and affection, suggesting that even the tiniest details of her lover are worth an epic journey.
Colombian superstar Shakira turns pure gratitude into an irresistible pop anthem with "Suerte" (Luck). The track is an open declaration of total infatuation across borders. She counts her blessings one by one, celebrating that her lover was born in the southern hemisphere with "Suerte que en el sur hayas nacido" (Lucky that you were born in the south) and that they can mock the physical distance between them. She goes all in on the devotion, claiming she would climb the entire Andes mountain range just to count his beauty marks ("escalar los Andes sólo / Por ir a contar tus lunares"). It is dramatic, passionate, and completely earnest.
What makes this track stand out are Shakira's delightfully witty, self-aware lines. Instead of relying on generic love clichés, she sings "Suerte que mis pechos sean pequeños / Y no los confundas con montañas" (Lucky that my breasts are small, so you do not confuse them with mountains). She also brings in colorful Spanish idioms that learners will love. When she sings "Sabes que estoy a tus pies" (You know I am at your feet), she means she is entirely devoted to him. Later, she admits "estoy hasta el cuello por ti" (literally 'I am up to my neck for you'), which is a vivid Spanish idiom meaning she is completely in over her head in love.
