Wham too forcefully finished popular song? (7)
I believe the answer is:
overhit
'wham too forcefully' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'finished popular song?' is the wordplay.
'finished' becomes 'over' (over can mean finished or ended).
'popular song?' becomes 'hit' (a hit song).
'over'+'hit'='OVERHIT'
Can you help me to learn more?
(Other definitions for overhit that I've seen before include "Shoot past the mark" , "used too much whip on" , "struck too hard" , "Perhaps putt past the hole" .)
