Zeppelin songs extremely cool (7)

I believe the answer is:

airship

I'm a little stuck... Click here to teach me more about this clue!

'zeppelin' is the definition.
(I've seen this before)

'songs extremely cool' is the wordplay.
'songs' becomes 'airs' (I've seen this in another clue).
'extremely cool' becomes 'hip' (hip can mean cool or fashionable. I am not sure about the 'extremely' bit.).
'airs'+'hip'='AIRSHIP'

Can you help me to learn more?

(Other definitions for airship that I've seen before include "Gas-filled craft" , "mode of flying" , "need approval from CAA" , "Blimp" , "Zeppelin, for example" .)

I've seen this clue in The Times and The Sun.
