Arrugue is a form of the verb arrugar, which means "to wrinkle". It's a wonderfully poetic word you don't often hear in pop songs.
In "La Lista", the singer describes his dream of growing old with his love, singing "Hasta que se arrugue nuestra piel" (Until our skin wrinkles). This tender image reveals that a lifetime of love is more important to him than any of the wild adventures on his bucket list.
La Lista swings with jazzy optimism as Aldrey rattles off a wild bucket list of skydives, exotic dishes, wolf-taming and elephant rides, yet every thrilling line circles back to a single truth: none of those headline-grabbing adventures means anything without the person he loves. The chorus stamps the message home—“Tú estás en el tope de mi lista”—making it clear that all dreams, from Eiffel Tower proposals to globe-trotting escapades, are really just backdrops for a deeper commitment. Fun bilingual rap breaks and globe-spanning imagery add sparkle, but the heart of the song is simple: the greatest adventure is building a life together, and the one memory that outshines parachutes and passports is holding hands with that special someone.
