Liking to write church music? (8)
I believe the answer is:
penchant
'liking' is the definition.
(I know that penchant is a type of liking)
'write church music?' is the wordplay.
'write' becomes 'pen' (synonyms).
'church music?' becomes 'chant' (chant is a kind of church music).
'pen'+'chant'='PENCHANT'
'to' is the link.
(Other definitions for penchant that I've seen before include "Inclination, bent" , "Fondness (for) - bias (towards)" , "Partiality" , "Leaning towards or liking for" , "Willingness" .)
