American Idol has already replaced Jennifer Lopez and Steven Tyler with Nicki Minaj and Mariah Carey. Now Randy Jackson is out. He will be a “mentor” whatever that means, and stay with the show in that capacity. Nicki is nothing more than a desperate attempt at a ratings grab, she is too new in the music industry to command respect, and her lack of defining a specific sound on one album, much less over her career isn’t something that people like out of artists. Mariah Carey is an amazing singer, so she can rest on that.
Randy is a respected producer, and very accomplished bassist. Without him the show loses a bit of credibility and shifts into a much younger demographic.
