Song’s chorus (7)
I believe the answer is:
refrain
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">song's chorus</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for refrain that I've seen before include "Stop oneself (from doing something)" , "Cease - repeated phrase" , "Abstain; chorus" , "Chorus; desist" , "Main part of song - do not do it" .)
