Novel published on Ray, jazz favourite (8,2,4)
I believe the answer is:
rhapsody in blue
'jazz favourite' is the definition.
I know nothing about this answer so I can't tell whether this works.
'novel published on ray' is the wordplay.
'novel' indicates an anagram (letters in a new or novel order).
'published'+'on'+'ray'='publishedonray'
'publishedonray' anagrammed gives 'RHAPSODY IN BLUE'.
Can you help me to learn more?
(Other definitions for rhapsody in blue that I've seen before include "Example of jazz" , "Gershwin's piece" .)
