Musical number with very little going for it (4)
I believe the answer is:
song
'musical number' is the definition.
(I've seen this before)
'very little going for it' is the wordplay.
'very little' says to take the initial letters.
'for' says to put letters next to each other (I've seen this in other clues).
'it' becomes 'son' (I am not sure about this - if you are sure you should believe this answer much more).
The first letter of 'going' is 'g'.
'g' after 'son' is 'SONG'.
'with' is the link.
Can you help me to learn more?
(Other definitions for song that I've seen before include "Ballad, aria" , "Ditty" , "You work best when on this" , "Words set to music" , "Piece of vocal music" .)
