Inne pieśni (Other Songs) is a novel written in 2003 by Jacek Dukaj, Polish science fiction writer.

The novel was well received by reviewers and critics, who commented on its original theme - an alternate Earth where the laws of physics, and philosophy, are different from that of ours.

However, a chain of events sets him off on a journey — first to Africa, and later into many new lands, from the depths of Warlock's domain, through the fabled Library of Alexandria and mysterious flying city, to the Moon colony, and on this journey he may have a chance of regaining his Form… Dukaj's primary influence have been the philosophical concepts of Aristotle, such as his conjectures on Form and Matter.

Among the influences, she counted classic science fiction form of Jules Verne, comparing his style to Dukaj's, particularly in the context of both descriptions and character's dialogues, focused on describing the fantastical world present.

Other influences she noted, particularly in the context of the exploration and adventure subplot, were those of Henryk Sienkiewicz and Joseph Conrad.
