As the title suggests it, this album reunites Alejandro Sanz's biggest hits between 1997 and 2004. It includes material from three studio albums: Más, El Alma Al Aire, and No Es Lo Mismo, and from the MTV Unplugged compilation. His biggest hit, "Corazón Partío," is included here as well some other popular songs like "Hay un Universo de Pequeñas Cosas," "Amiga Mía," "No Es Lo Mismo," "Quisiera Ser," and what is probably his best song, "Cuando Nadie Me Ve." There's also one new song: "Cuando Sea Espacio." This album is the perfect companion to the Grandes Éxitos 91_96. It's perfect as a sample of Sanz's work. ~ Iván Adaime, All Music Guide
