Release this song from Disney film (3,2,2)
I believe the answer is:
let it go
'release this song' is the definition.
'let it go' can be an answer for 'song'. I'm unsure of the remainder of the definition.
'disney film' is the wordplay.
I cannot really understand how this works, but
'film' could be 'it' and 'it' is found within the answer.
The remaining letters 'letgo' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'from' is the link.
Can you help me to learn more?
(Other definitions for let it go that I've seen before include "Disney tune" , "Refrain from comment" , "Hit song from Disney's 2013 animated feature film Frozen" , "Excuse something" .)
