Sheikdom of song (5)
I believe the answer is:
araby
'sheikdom of song' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for araby that I've seen before include "The Sheik of --, music hall song" , "Poetic land of sheikhs" , "poetically-named hot land?" , "peninsula described in poetry" .)
