Some quasi-renewed rock singer? (5)
I believe the answer is:
siren
'rock singer?' is the definition.
(I've seen this in another clue)
'some quasi-renewed' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'SIREN' is hidden within 'quasi renewed'.
(Other definitions for siren that I've seen before include "Alarm; temptress" , "Nymph supposed to have lured sailors to destruction on rocks" , "Warning sound" , "Dangerously fascinating woman" , "Alluring female" .)
