Sampling of songs (6)
I believe the answer is:
medley
'sampling of songs' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for medley that I've seen before include "Composition of a series of various musical pieces" , "Piece of music made up from various other pieces" , "Compilation of song extracts" , "Various tunes combined in one piece" , "Music combining a number of songs" .)
