Blows; successes (4)
I believe the answer is:
hits
I believe this clue is a double definition.
'blows' is the first definition.
(I know this)
'successes' is the second definition.
(hit is a kind of success)
(Other definitions for hits that I've seen before include "Top pops" , "Pop successes" , "welcome in the theatre world?" , "In the 60s these were 'groovy'" , "The sort of strikes" .)
