The Welsh singer said he is hoping to finish the show's run of three consecutive festive chart toppers with his charity single 'Little Drummer Boy/Peace On Earth'.
The track, which features fellow Radio 2 DJ Terry Wogan, will raise funds for Children In Need.
"Chris Evans heard it and proclaimed to the nation that it was his ambition to make it the Christmas number one as the antidote to X Factor," Jones told DS.
"I think the words he used were, let X Factor be number one for 51 weeks of the year, but for just this one, let's have something Christmassy and sentimental."
He continued: "Anything that challenges the norm is great, I think. X Factor has a monopoly on it. The fact is that I don't see this as a novelty song, it's not 'Bob The Builder'. This is a little bit more serious and we put our heart and soul into it."
Commenting on Wogan's vocal contribution, Jones joked: "I think he may have been having sneaky lessons. I think if you have a listen to ‘Floral Dance’ and then listen to this, he's much better on this. He's aged like a fine wine."
X Factor winners Leon Jackson, Leona Lewis and Shayne Ward landed the last three Chirstmas top spots.
