Ill have to come back to the playback issue again...Do people really take the rules seriously? Theres a rule to have a maximum of 6 people on stage, many acts break it, theres a rule to have no backing voices from playback, most break it and theres the rule to have no playback singing, some break it, I'll try to show it with videos...
This one is the most obvious rule-breaking i saw when browsing youtube a few minutes ago, im too lazy to rewatch all performances though, this guy from greece breaks the backings rule

He has male and female backings and 4 dancers, so if the backings are playback, he broke the no-backings-playback rule, if they are live and the singers hide somewhere(unlikely xD) he broke the 6 persons rule^^
that should show all the people with the rules-thing that the rules arent taken serious at all, I have no idea if he sings live(you cant sing on such a mic without really strong mic noises and i cant hear mic noises, but i cant hear much anyway because youtube quality is poor, so i wont make a statement about him singing playback)
