Varied mixture (6)
I believe the answer is:
medley
'varied mixture' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for medley that I've seen before include "Compilation of song extracts" , "Musical mixture" , "Piece combining music from various sources" , "Group of songs played as one piece" , "A succession of tunes played continuously" .)
