Record drop is broadcast (8)
I believe the answer is:
disclose
'is broadcast' is the definition.
(I've seen this before)
'record drop' is the wordplay.
'record' becomes 'disc' (eg a CD, compact disc).
'drop' becomes 'lose' (I've seen this in another clue).
'disc'+'lose'='DISCLOSE'
(Other definitions for disclose that I've seen before include "Make public" , "Announce" , "Divulge or expose" , "broadcast" , "Uncover" .)
