If you had the choince what songs would you sing if there were no themes.

This could be aired and then at least we would have an idea about what sort of artist they would like to be.

We do not know what Sam B likes or Nicholas for that matter.

They have no choice in the songs but could surprise us if they could sing their own choices

If only. I have said since Day that I would like to know what sort of artist Nicholas sees himself being - surely he doesn't want to be a mini Buble???

Does that mean you'd vote for them based on whether you like the artists they happen to mention? Or would you still judge them on the merits of their performances? If the latter, why do you need to know the former?
