wothout doubt! also many of the initial auditions are staged also - some people go on knowing that if they are really bad they will get on TV and might get some other media interest of the back of that - classic example was that Irish guy with the quiff and long bleached blonde hair - think his name was Brendan.
Also not sure if any of ye will seen this guy but you might have if you have ITV2 but there was a chinese guy on American Idol that was terrible and he was sooooo bad that they gave him a contract due to the comedy factor and I think he might have gone to no. 1 with it!! just shows ya!
