Oropeles literally translates to "tinsel" or "glitter", but it often carries a deeper meaning of "pomp" or "showy display" that lacks real substance.
In this song, the narrator's friend "augurabas oropeles y ultramares" (predicted tinsel/pomp and overseas adventures) for him. It's an interesting word choice because it suggests not just success, but perhaps a flashy, glamorous kind of success, hinting at the allure and potential superficiality of fame in the music world.
Have you ever had a crazy night out with friends that completely changed your life? Jorge Drexler's "Pongamos que hablo de Martínez" (Let's say I'm talking about Martínez) is a heartfelt thank you to a friend who, during a wild, drunken night in Montevideo, gave him some truly life-altering advice.
He remembers closing four bars one by one as the sun came up, and his friend, full of grand predictions, told him he'd find "oropeles y ultramares" (tinsel and overseas). Drexler admits he was "preso en mi alegría diletante" (trapped in my dilettante joy) and, taking his friend's "consejo delirante" (delirious advice), he headed to Madrid with his guitar and songs. Now, 22 Decembers later, he's finally writing this song to say thank you. He knows his friend, with his "empaque de alatriste" (Alatriste-like demeanor), might be embarrassed by a "confesión de borrachera" (drunken confession), but Drexler insists, "el regalo que me hiciste me cambió la vida entera" (the gift you gave me changed my whole life). He even cleverly disguises his friend's name, saying, "para nombrar a quien estoy agradecido, pongamos que hablo de Martínez" (to name the one I'm grateful to, let's say I'm talking about Martínez).
