^ They've probably turned down alot of good singers over the years because the show isn't about "just great singers" it's about putting together a group of diverse people who are polarizing enough to attract an audience and then generate that over top fanaticism they want to keep them coming back week after week, otherwise, really why would Sanjaya ever even have made it to the semi's? Some years they do a great job like season 5 and some years they really don't hit the mark like Season 3.
