"Molinos de viento" ("Windmills") is a single from the Spanish folk metal group Mägo de Oz[1][2] and is their most famous and widely known song.
This track belongs to their 1998 album La Leyenda de la Mancha, but it was released as a single in 2002 from their live album Fölktergeist with the single "El lago".
This song talks about a conversation between Don Quixote and Sancho Panza, where the first reprehends the latter about his pessimism and his lack of belief.
However, Don Quixote's idealism and Sancho's pessimism is a principal theme on it.
In 2006, the group recorded the song again for their compilation album The Best Oz.
