Get listener's attention, finally (4)
I believe the answer is:
earn
'get' is the definition.
(earning is a kind of getting)
'listener's attention finally' is the wordplay.
'listener' becomes 'ear' (I've seen this before).
'finally' says to take the final letters.
The final letter of 'attention' is 'n'.
'ear'+'n'='EARN'
(Other definitions for earn that I've seen before include "Be paid for work" , "Win" , "long gone" , "Gain credit from" , "Deserve; get paid" .)
