Leona Lewis wrote new track Glassheart to make her "dance and jump around".The Collide singer worked with Ryan Tedder - the OneRepublic singer and songwriter responsible for her biggest hit, Bleeding Love - on the title track from her new album and wanted it to be an upbeat song.
She told Digital Spy: "Glassheart we wrote, I remember, when I was a little bit down. I went to Denver to hang out with Ryan - to see him and his family - and see if we could come up with something nice.
"I remember just not wanting to sing a ballad or anything that would make me more sad.
"I was like, 'Can you give me a song where I can just dance and jump around?', and he was like, 'What about this?' - he played this beat and it was really hypnotic. So I was like, 'Yes! We have to do this'."
Leona says her third album is an "eclectic mix" of genres, with one stand out track being called Trouble, which has a "trip-hop" beat to it.
She added: "I think Trouble will be the second single. I can't wait for everyone to hear it. I'm really excited about it. It's one that I really love.
"It's got an element of Massive Attack in it. A bit of trip-hop, a bit of flavour - I've just never heard anything like it, which is why I was like, 'This is very cool'."
Leona's album Glassheart is released on 28 November.
