"Algo Está Cambiando" (English: Something is Changing) is the third single from the Mexican singer Julieta Venegas off her third studio album Sí.

The song was written by Coti Sorokin and Julieta Venegas occupying the first places of the Billboard charts, is positioned at the top at number one in Spain, Argentina and Mexico.

The video, recorded by Rigoberto Castañeda, shows Julieta entering an apartment where she carelessly throws her keys to a wooden table, removes her pink jacket placing it on a chair in the hallway and hurries to answer the phone, accidentally breaking a long, white vase in the process. She briefly speaks on the phone and then hurries to take her jacket and keys while a still take of a photograph of a groping couple is shown as she puts the jacket back on and leaves the apartment just to come right back in.

She repeats the same sequence of actions, but the key chain, vase and most of the furniture changes in color and style. A photograph of the same couple sitting further away but smiling is shown, then the singer leaves the apartment to reveal a couple of copies of her with different clothes hanging from the coat stand singing and moving their feet rhythmically.
