Wastes time with key friends (7)

I believe the answer is:

dallies

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

'with key friends' is the wordplay.
'with' says to put letters next to each other.
'key' becomes 'd' (musical key).
'friends' becomes 'allies' ('ally' can be a synonym of 'friend').
'd'+'allies' is 'DALLIES'.

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

I've seen this clue in The Mirror.
