I ask this as I have seens so many post about "I want to see what they are like doing a slow/fast rocky/ballad/pop song".
Then as soon as someone attempts something outside of their normal set and it goes less than absolutely prefect, they are jumped on and savaged by many on here.
So why does the winning act have to be and all-rounder when as soon as they start recording, they will be doing what is correct and right for them.
Acts that you may not like, but who have made millions by sticking to what they are good at:
Westlife - a whole career based on over-the-top love songs.
Barry Manilow - Much the same!
Guns 'n' Roses - Rock with a voice that can break concrete.
and so so so many more!
Even the greatest artists of all-time when doing their version of an old song, have done just that: THEIR VERSION.
I.E. The original version didn't suit them!
So if it's good enough for the greatest artists of all-time, then why do the X-Factor contestants HAVE TO be all-rounders?
David Copperfield is an Illusionist - rarely does he do just do an Escapology trick or hypnotise people. He sticks to what he does best.
