Dad's kind of music? (3)
I believe the answer is:
pop
This clue is a double definition.
'dad's' is the first definition.
(synonyms)
'kind of music?' is the second definition.
(Other definitions for pop that I've seen before include "Sound of a drawn cork" , "Burst - fizzy drink - modern music - US dad" , "Explosive sound; drink" , "Sound of a balloon bursting" , "Music with mass appeal" .)
