In all honesty, as one of the best singers on the planet, I think Nicki was the best judge to happen to America Idol ever. I'm one of the toughest critics when it comes to singing talent and I love when people are brutally honest if it's coming from an authentic place and not a place of malice or jealousy. Mariah could've been a great judge , but was too afraid to bruise her brand and be honest and thoroughly critical to contestants. Nicki said mostly what I would have to contestants, although I'm alot tougher than she. But, I would love to see her for another season and the producers probably would too, but America is not that in love with Nicki which is probably why she won't return.
