Well, I guess it was bound to happen. This past saturday Deadmau5 had to step in and take place for Avicii who fell sick last week to close out Ultra Day 2. But some are criticizing one remix he played. Seventeen year old Martin Garrix song "Animals" was easily the most played and remixed song of the festival this week but Deadmau5's remix of it caused some controversy. Deadmau5 chose to play a mix previously made by another producer that was set to the tune of "old mcdonald." Some have said its all in good fun and just some hazing of the new guy from a seasoned vet. But others, such as mega dj Tiesto, are calling it disrespectful. What do you think?
