Record of Hungarian composer broadcast (4)
I believe the answer is:
list
'record' is the definition.
(list is a type of record)
'hungarian composer broadcast' is the wordplay.
'hungarian composer' becomes 'liszt' (I've seen this before).
'broadcast' shows a homophone (sound like) (how the word might sound on the radio or TV).
'liszt' is a homophone of 'LIST'.
'of' acts as a link.
(Other definitions for list that I've seen before include "Heel - catalogue" , "Item-by-item record" , "Itemised catalogue" , "pay heed no longer" , "Pay attention" .)
