Country song containing line for one on the rebound (7)
I believe the answer is:
algeria
'country' is the definition.
(I know that Algeria is a African country)
'song containing line for one on the rebound' is the wordplay.
'song' becomes 'aria' (piece of music in an opera).
'containing' means one lot of letters goes inside another.
'line' becomes 'l' (used when specifying particular lines from a poem).
'for one' becomes 'eg' (both can mean 'for example').
'on the rebound' says the letters should be written backwards (to rebound is to go backwards).
'eg' reversed gives 'ge'.
'l'+'ge'='lge'
'aria' enclosing 'lge' is 'ALGERIA'.
(Other definitions for algeria that I've seen before include "Land" , "Strange regalia of a North African state" , "It lies between Morocco and Tunisia" , "North African country" , "country in Africa" .)
