We caught up with Goulding to talk about the expanded reissue of her 2012 album, Halcyon, as Halcyon Days, now bolstered with 10 additional new songs and set for release next Tuesday, August 27.

"It's a little happier than everything I've done before," Goulding said of the new songs featured on Halcyon Days. "It's kind of the more uplifting songs. It embraces my love of electronic music a bit more. I've got collaborations on there with DJ Fresh, Greg Kurstin, Nate Ruess from fun.

"Basically, after my album came out, it's been a weird time for me," she continued. "I feel like now I'm so much deeper into Halcyon that I just wanted to expand it. I wanted it to last longer, because I'm not done with this record yet. For anyone else, it might be a time to move on and make another record, but I don't think it's the end yet."

The new clutch of songs was led by the single "Burn," which has the distinction of being Goulding's first No.1 song in her home country of Great Britain.

"'Burn' I wrote with Ryan Tedder, and I love it. It's something different for me," she enthused. "It has a different rhythm, it's a different kind of vibe and I really enjoy performing it and singing it. I did a Vine video where I got all of my fans to do their own interpretation of 'Burn' and what the song meant to them. Then I did my own video featuring lots of kids wanting to be in a music video, and then (multiply) them by like a thousand. We did it on an airstrip. It was just a bunch of us having fun, and that's kind of what I wanted to do."
