Urban joked to "Extra" he tried to be "Switzerland" during the highly publicized incident, adding the dust-up didn't make him sorry he had joined the judges' panel, which also includes "Idol" veteran Randy Jackson.
"I love it, I gotta say," Urban said. "I love working with passionate people. I love artists. Everyone just sort of expressing themselves. It's a very alive and very invigorating work environment. A lot of passion."
