Wastes time on key comrades (7)

I believe the answer is:

dallies

'wastes time' is the definition.
(I've seen this before)

'on key comrades' is the wordplay.
'on' says to put letters next to each other.
'key' becomes 'd' (musical key).
'comrades' becomes 'allies' (I've seen this in another clue).
'd'+'allies' is 'DALLIES'.

(Another definition for dallies that I've seen is " wastes time".)

I've seen this clue in The Mirror.
