Cut down consuming to hit factory in America (6)
I believe the answer is:
motown
'hit factory in america' is the definition.
(US record label behind various hit records)
'cut down consuming to' is the wordplay.
'cut down' becomes 'mown' (I've seen this in another clue).
'consuming' is an insertion indicator.
'mown' placed around 'to' is 'MOTOWN'.
(Other definitions for motown that I've seen before include "Detroit's musical export" , "Genre of music originally from Detroit" , "Detroit, the car city" , "form of music" , "Detroit musical style" .)
