Carol Deng's new lullaby? (10)

I believe the answer is:

cradlesong

'lullaby?' is the definition.
('cradlesong' can be a synonym of 'lullaby')

'carol deng's new' is the wordplay.
'new' indicates an anagram.
'carol'+'dengs'='caroldengs'
'caroldengs' with letters rearranged gives 'CRADLESONG'.

(Another definition for cradlesong that I've seen is " Lullaby".)

I've seen this clue in the Sydney Morning Herald.
