The album has to get better (4)
I believe the answer is:
heal
'get better' is the definition.
('heal' can be a synonym of 'get better')
'the album has' is the wordplay.
'has' indicates the answer is hidden within the clue.
'HEAL' is hidden within 'the album'.
'to' is the link.
(Other definitions for heal that I've seen before include "Make whole and healthy" , "Cure, make well" , "Get healthy again" , "Get well again" , "Of wound, mend and get better" .)
