Sophie Ellis-Bextor has relished the recent success of 'Murder on the Dancefloor'.

The 44-year-old singer released the pop hit in December 2001, and it's enjoyed a revival over recent months, after it was featured in 'Saltburn', the Emerald Fennell-directed thriller film.

Sophie told 'Newsbeat': "It actually feels really magical. And if I'm honest, I don't think I've completely processed it really.

"It's extraordinary. It's a song I've been singing for over 20 years, I still love singing it.

"I love the way people react when I do it live.

"But for new people to be discovering it, for it to be making new memories with people is kind of beautiful."

Emerald, 38, asked for permission to feature the track in her movie, which starred Barry Keoghan, Jacob Elordi and Rosamund Pike.

But Sophie never expected 'Murder on the Dancefloor' to re-enter the charts.

She said: "One of the things I never prepared for is the fact that when you release anything into the world, any new music, it goes off and has its own journey.

"And you're along for the ride a bit, it also goes places you're not expecting to go.

"So what's happened with the song and how it's got new people who weren't even alive the first time it came out listening to it, it's just spectacular."

'Saltburn' features some X-rated scenes, and Sophie found watching the movie alongside her mum and her 19-year-old son Sonny to be an awkward experience.

The pop star shared: "I wasn't worried about my mum, I was worried about how my son was feeling about being between his mum and his grandma while he's watching all these scenes.

"But he was fine. He was like 'that was in my top ten favourite films I've ever seen'.

"I was sort of projecting my worry on him but I did have my head in my hands at least twice during the film - you can probably guess the two bits when."
