Pretentious songs? (4)
I believe the answer is:
airs
'songs?' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for airs that I've seen before include "'Tunes, melodies (4)'" , "Ventilates, say grievances" , "Pretentiousness" , "songs" , "Voices" .)
