When Fijación Oral, Vol. 1 hit stores in 2005, Shakira was on top of the world. She'd gained legions of devoted Latin American fans with a decade of generation-defining anthems on albums Pies Descalzos and Dónde Están Los Ladrones and swung big for the U.S. and European markets with her first English-language record, Laundry Service, at the turn of the millennium. Her gamble paid off, and enormous hits such as “Whenever, Wherever” and “Underneath Your Clothes” made her a household name around the globe. But the deliberate commercial intent behind Laundry Service also created some unease that the stargazing, raven-haired poet of the ‘90s had been usurped by a blonde pop princess for the Y2K generation. In order to placate the whispers in her ranks, and without any intention of conceding her progress toward global domination, Shakira undertook a gargantuan two-part album cheekily dubbed Fijación Oral, or . For the project, the pop behemoth wrote over 60 songs and enlisted hitmaker Rick Rubin as executive producer. The 10 original songs that made it on Fijación Oral, Vol. 1 glanced back nostalgically on Shakira's early catalogue of rock-driven hooks and burning ballads, notably on love-addiction slow burn “La Pared” and the effervescent affirmations of “Día de Enero”. She also enlisted some of her biggest contemporaries, collaborating with Argentine rock god Gustavo Cerati on “No” and “Día Especial” and tapping Spanish crooner Alejandro Sanz for “La Tortura”. Her duet with Sanz was the album's lead single and biggest hit, melding rock, tango and reggaetón and becoming one of the first songs in Spanish ever performed at the MTV Video Music Awards, sharing the night with Daddy Yankee's “Gasolina”. Fijación Oral, Vol. 1 also includes many of Shakira's first nods to camp: donning purple wigs in the surrealist video for synth-pop banger “Las de la Intuición”, cooing in Marilyn Monroe-esque fashion on “Obtener un Si”, and playing up the bombshell tropes on “Escondite Inglés”.
