Amy Winehouse hit (5)
I believe the answer is:
rehab
'amy winehouse hit' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rehab that I've seen before include "brief convalescence?" , "Alcohol clinic" , "Treatment for alcohol abuse" , "Treatment for alcohol or drug dependence" , "Rehabilitation (abbrev.)" .)
