"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.

The sequence repeats itself twice, with Julieta becoming increasingly careless with the way she throws the keys and breaks the vases, and dismissing such things as unimportant; showing pictures of the couple sitting further away and ignoring each other, and adding a new copy of her on the hanger each time.

The fifth time she comes back in, most of the furniture is gone, so Julieta decides to hang on to her keys and puts them in her pocket, throws her jacket on the floor and dances happily to the phone.
