Songbird in favour of shoddy stuff like petty revenge (3,3,3)
I believe the answer is:
tit for tat
'petty revenge' is the definition.
'tit for tat' can be an answer for 'revenge' (I've seen this before). I am unsure of the 'petty' bit.
'songbird in favour of shoddy stuff' is the wordplay.
'songbird' becomes 'tit' (tit is a type of songbird).
'in favour of' becomes 'for' (being for a particular cause).
'shoddy stuff' becomes 'tat' (I've seen this before).
'tit'+'for'+'tat'='TIT-FOR-TAT'
'like' is the link.
Can you help me to learn more?
(Other definitions for tit for tat that I've seen before include "Retaliation in kind" , "Appropriate retaliation" , "In annoyance, return" , "satisfaction" , "revenge" .)
