As a singer (not an X-factor contestant EVER I add), I have a lot of friends that have entered and got quite far. Also however, a lot of really talented, amazing vocalists that haven't got past the gate.
Apparently, there's 5 sets of auditions infront of panels and producers before you even get to the stage. Obviously they're filtered. The judges could never see 20,000 people or however many audition every year. Because of this, there's obviously a lot of people that get through to the judging stages based on their entertainment factor/really bad audition.
If you watch the Xtra factor you might have seen her but keep an eye out for Jo Beetlestone. She got through to boot camp last year and is through again this year. Incredible voice. Gary loved her.
Also, there doesn't seem to be many bands at all this year. A few but not like previous years.
