Gypsy Chorus sampled for Thriller (6)
I believe the answer is:
psycho
'thriller' is the definition.
(I've seen this before)
'gypsy chorus sampled' is the wordplay.
'sampled' says the answer is hidden in the clue (I've seen this in other clues).
'PSYCHO' can be found hidden inside 'gypsy chorus'.
'for' is the link.
(Other definitions for psycho that I've seen before include "1960 thriller starring a deranged Anthony Perkins" , "Hitchcock's 1960 classic chiller" , "Bates Motel horror film" , "Hitchcock classic" , "Well-known Hitchcock film" .)
