After a couple of days rumination, rated by difficulty of decision.

one work of non fiction = 'Godel Escher Bach' by Douglas Hofstader

(medium)
a photograph of an artefact or a work of art = Number 1 by Jackson Pollock

(hard)
one novel = 'Lord Jim' by Joseph Conrad

(nigh on impossible so pretty much picked at random from about 20)
CD album (no compilations) = Sisters of Mercy - Some Girls Wander By Mistake
