Collections of photos or music (6)
I believe the answer is:
albums
'collections of photos or music' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for albums that I've seen before include "Blank book (for stamps)" , "Stamp collector's books" , "LPs, CDs" , "Books of blank pages, for photographs say" , "Photograph books" .)
