Tinsel arrayed, almost time for this song? (6,5)
I believe the answer is:
silent night
'tinsel arrayed' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'almost time for this song?' is the wordplay.
'almost' becomes 'nigh' (nigh can mean almost or nearly).
'time' becomes 't' (abbreviation).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'this song?' becomes 'silent' (I can't justify this - if you can you should believe this answer much more).
'nigh'+'t'='night'
'night' after 'silent' is 'SILENT NIGHT'.
Can you help me to learn more?
(Other definitions for silent night that I've seen before include "Blood sucking mammals" , "Christmas carol - hours of undisturbed sleep?" .)
