Meaning 'pound', it gets pounded (4)
I believe the answer is:
beat
'meaning pound' is the definition.
'beat' can be an answer for 'pound' (I've seen this before). I am unsure of the 'meaning' bit.
'it gets pounded' is the wordplay.
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'gets' is an insertion indicator.
'pounded' becomes 'bat' (I can't explain this - if you can you should give a lot more credence to this answer).
'e' put within 'bat' is 'BEAT'.
Can you help me to learn more?
(Other definitions for beat that I've seen before include "Throb; surpass" , "Rhythmic music unit" , "club" , "Musical rhythm" , "Rhythmic musical unit" .)
