Sólo Tres and Ojalá

Our favourite Zihua trio, Sólo Tres, sings a beautiful song, "Ojalá". I've been unable to find this song on Spotify. There appear to be several songs of the same name, or song titles that include the word "Ojalá", but none that match the version Sólo Tres sings.
Does anyone know who popularized this song, so I can download it?
