Music with 'go' (3)
I believe the answer is:
pop
I believe this is a double definition.
'music' is the first definition.
(pop music)
'go' is the second definition.
(popping is a kind of going)
'with' is the link.
(Other definitions for pop that I've seen before include "Thus goes the weasel in children's rhyme" , "Youthful music, dad(3)" , "Cartoon sailor (showing amazement?)" , "Music with mass appeal" , "Thus goes the musical weasel" .)
