Even though Keith Urban has only been a judge on 'American Idol' for one season, which is winding down as we speak, his quiet and kind demeanor has already made him a fan favorite.

In fact, Urban was recently voted 'Best Idol Judge Ever' in a Zimbio readers poll. In the poll of 1,200 Zimbio readers, the majority of people chose Urban as the best 'Idol' judge. The results are surprising in some ways, since the country crooner isn't the most vocal person sitting on the judge's panel. He leaves that role to Nicki Minaj, who has been known to make some quippy remarks to contestants on the show that are along the same lines as former judge Simon Cowell, for those who haven't tuned in to this season yet.

The 'Long Hot Summer' hitmaker isn't one to destroy a contestant's confidence with harsh words or sarcasm. Instead, he offers hopeful stars kind words of advice and thoughtful feedback.

As for whether or not he'll return for another season of the show? “We haven’t confirmed anything, but we needed to leave some holes there, in case another season happens,” he says. “If we do another season, those would be where the audition cities would go. But nothing’s confirmed at all.”

The poll included judges from all seasons of the show, so old favorites like Simon Cowell and Paula Abdul were a part of the competition, as well. Check out the rankings:
