Sam Smith is lending his GRAMMY-winning vocals to the beloved James Bond film franchise, but can his Spectre theme song live up to Adele's Skyfall hit?

The 23-year-old singer debuted "Writing's On the Wall" early Friday morning, and it's a bit of a detour from his usual R&B hits.

"If I risk it all, could you break my fall?" Smith croons in the somber tune. "How do I live? How do I breath? When you’re not here I’m suffocating. I want to feel love flow through my blood, tell me is this where I give it all up. For you, I have to risk it all. Because the writing’s on the wall."

The "Stay With Me" singer was understandably nervous for people to hear it, joking that it "could be a pile of crap."

"To be honest, it hasn't set in yet," Smith told special correspondent Elvis Duran backstage at the iHeartRadio Music Festival. "I keep looking at that Wikipedia page and just seeing my name on it -- and it's unreal."

Adele was the last artist to sing a theme song for the film franchise, and it earned her an Oscar, GRAMMY and Golden Globe. "Skyfall," named after the movie itself, was the first Bond song to sell a million digital copies.

And just like his female counterpart, who reportedly wrote "Skyfall" in 10 minutes, Smith and co-writer Jimmy Napes penned his theme in record time. "About 20 minutes," he revealed. "It came so naturally, with me and Jimmy -- we're still nervous. We're not sure people are going to love it or hate it."
