"Salvapantallas" is a love song built out of tiny, everyday details. Jorge Drexler opens with "Tengo tu voz, tengo tu tos" (I have your voice, I have your cough), which is a funny and very tender thing to treasure about someone. The two of them are "Rumbos paralelos, dos anzuelos en un mismo río" (parallel paths, two fishhooks in the same river): separate, but going the same way.
The title is the best joke. A salvapantallas is a computer screensaver, and he says "Tengo tu sonrisa en un rincón de mi salvapantallas" (I have your smile in a corner of my screensaver). In between, he invites her to the sea, to dar cuerda a antiguas vitrolas (wind up old gramophones; vitrola is the Latin American word for a record player), to pedal against the wind and against time, soltando amarras (casting off the moorings, a sailing image for letting go). He even raises a glass to the battles they lost together: "Brindo por las veces que perdimos las mismas batallas" (I toast to the times we lost the same battles).
