Country songs sent up with limp content (3,5)
I believe the answer is:
sri lanka
'country' is the definition.
(Sri Lanka is an example)
'songs sent up with limp content' is the wordplay.
'songs' becomes 'airs' (I've seen this in another clue).
'sent up' says the letters should be written backwards.
'with' is an insertion indicator.
'limp content' becomes 'lank' (I am not sure about this - if you are sure you should believe this answer much more).
'airs' backwards is 'sria'.
'sria' enclosing 'lank' is 'SRI LANKA'.
Can you help me to learn more?
(Other definitions for sri lanka that I've seen before include "Island by Southern India" , "Ceylon since 1972" , "land" , "[TEST TEAM]" , "cricket side" .)
