Not just the best song of the album ...

... But a nice catchy chorus, so that success is guaranteed. "Volverte a ver es todo lo que quiero hacer" is certainly not a highlight of Spanish poetry, but for everyone who has ever attended a few courses at the VHS, or as a reminder of the exchange semester art history at the University of Salamanca, it is good for all.
After all, "A Dios le Pido" on the Maxi-CD, is still the best song of Juanes (and unfortunately remains the only real classic by him).
