Songs from Carlos (6)
I believe the answer is:
carols
'songs' is the definition.
(carol is a kind of song)
'from carlos' is the wordplay.
'from' indicates an anagram (from the letters).
'carlos' anagrammed gives 'CAROLS'.
(Other definitions for carols that I've seen before include "Traditional Christmas songs" , "Seasonal songs" , "Special songs for Christmas" .)
