that is up there, one of the things anyone auditioning for the x factor should do before ever going before the judges is practice there auditions a lot, but
.....in front of other people like friends and family.
like doing mock auditions.
that would help break the illusion that they are a good singer, or for a lot, if they just practice in the mirror with a hair brush as there only preparation for auditioning, i think that is what is causing this kind of illusion in there heads.
though of course the x factor does like to let through a few hopeless cases for live auditions before the judges...
you wonder if it is fair to laugh at these deluded hopefuls?
