Not sure if young Madeon is shooting at Nicky or just speaking in general but, what we do know is that they both have a point.

@nickyromero Exactly ! Spend 100k on a ghost producer instead.

UPDATE:
Madeon did not aim at Nicky with his comment.

@StoneyRoads Huh, no ! @nickyromero is an awesome guy and a real producer. That joke wasn't aimed at him at all.
