Is there a list anywhere of the Samorost 1 source tracks?
None... as yet.
Somewhere I found the title "Land Of Rice" associated with the scene of the hookah smoker.
Maybe it was here? 2016:link is now dead
(Note: the author at that site is wrong about Tomáš Dvořák having written the composition. The Samorost 1 soundtrack was put together by Jakub Dvorský while he was finishing up his university studies... before
he and Floex began working together at Amanita Design)
As for discussions here on the forum regarding the Samorost 1 tracks, see topic: Music from Squirrel level
And also: dnb track at samorost 2. [correction: topic is about Samorost 1]
Good luck finding the rest of the original source tracks!
