If the "Idol" producers were to consider making an industry expert one of the new judges, they should promote Jimmy Iovine.

Simply put, he's a respected vet with a sharp tongue. Sound familiar? If a replacement for Simon Cowell is what they're looking for, they really don't have to look all that far.
