Musical potpourri (6)
I believe the answer is:
medley
'musical potpourri' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for medley that I've seen before include "Composition of a series of various musical pieces" , "Melange" , "A succession of tunes played continuously" , "Piece of music comprising various tunes" , "Number of tunes put together" .)
