I feel like the judges' guesses last season were more genuine, and this season it does seem like they are being fed names from the producers.
Although since none of them have guessed Chris Daughtry for Rottweiler yet, and none of them got T-Pain last season, maybe that means they are setting up Rottweiler for the win?
I think this season has had better talent overall, but I thought last season's top 5 was better than this season.
