Sam Smith's new James Bond theme song, "Writing's on the Wall," is predicted to be the first track of its kind to land at No. 1.

The track, which was created specifically for the upcoming film "Spectre," has doubled the sales of its closest competitor, Justin Bieber's "What Do You Mean?" according to BBC News.

While it may seem surprising, no Bond theme has ever made it to the top of the chart in the U.K. before. Out of all 23 Bond themes, those that came the closest peaked at No. 2, including Adele's "Skyfall" and Duran Duran's "A View To A Kill."

The new Bond theme from Smith has received mixed reviews from critics.

Sir Roger Moore, who played Bond from 1973 to 1985, thought Smith's theme song was "very haunting and wonderfully orchestrated." On the other hand, BBC entertainment correspondent Colin Paterson said the song was "good enough, but not classic," making sure to acknowledge that it is still much better than Madonna's theme song for 2002's Bond film "Die Another Day."

Smith's theme is the first recorded by a British male solo artist since Tom Jones' theme for 1965's "Thunderball."

Talking with Nick Grimshaw on BBC Radio 1, Smith himself had doubts the theme song could reach the heights of No. 1.

"I don't think it's a No. 1 friendly song if you know what I mean," Smith said to Grimshaw last week. "Who knows, but I don't think it will [get to No. 1] at all -- but I'm not looking for that."

Barbara Broccoli and Michael G. Wilson, the producers of "Spectre," have praised the new theme song, labeling it "one of the greatest Bond songs of all time."

"Spectre" is scheduled for release in U.S. theaters on Nov. 6.
