German song wasn't honest (4)
I believe the answer is:
lied
'german song' is the definition.
('song' in German)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for lied that I've seen before include "German romantic recital piece" , "German air" , "untrue" , "Spoke falsely" , "Told an untruth" .)
