Having a chat to BBC Newsbeat the 'Believe' interpreter highlighted the fact you can walk on stage with a guitar as a sign of how much the show has developed.
"A lot of it has changed as well. You can go on there with an instrument," she said. "You can play and there's just a lot more artistry to the show and that's great."
Another sign of the show's development is of course Intense Troubadour James Arthur.
"We've got somebody like James Arthur, who won and he's an incredible talent," she mused. "Everybody was so different this year and so diverse and I think it just shows the show is a credible show at the end of the day and that people have come off it who really do take music seriously."
