Most of the contestants are better singers than the judges imo.
Yes, I'm looking at you Will.i.am with your ridiculous full stops. You are a great musician and rapper but you can't sing for toffee.
I've always thought Tom Jones is over-rated. He can belt out a tune OK but there's no range there, is there.
Jessie J is competent, but not to my taste.
And as for the other one. Well if he was any good, surely I would have heard of him before he was signed up for the programme.
