Love the noise of a Norse god (4)
I believe the answer is:
odin
'a norse god' is the definition.
(Odin is an example)
'love the noise' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'the noise' becomes 'din' (din can mean a loud noise or disturbance).
'o'+'din'='ODIN'
'of' acts as a link.
(Other definitions for odin that I've seen before include "Supreme god of Scandanavian myth" , "God - I nod (anag)" , "Supreme god of war in Norse mythology" , "The supreme Norse god and creator" , "Pagan god" .)
