Figure — song (6)
I believe the answer is:
number
I believe this clue is a double definition.
'figure' is the first definition.
(I've seen this before)
'song' is the second definition.
(I've seen this in another clue)
(Other definitions for number that I've seen before include "28 down, for instance" , "theme tune?" , "Cardinal or ordinal" , "(Symbol for) quantity" , "comparatively lacking in feeling" .)
