Coldplay has debuted another song off upcoming album “A Head Full of Dreams”. Chris Martin shared “Everglow,” which features guest vocals from Martin's ex-wife Gwyneth Paltrow, on Zane Lowe's Beats 1 radio show.

Martin explained to Lowe that the song's title is a word he learned from a surfer.

The Coldplay front-man told Rolling Stone magazine that the song is “about a relationship's enduring spark.” Regarding Paltrow's vocal contributions to the track, Martin said, “We just did it in the studio one day. It was just a friendly kind of thing.”

 “A Head Full of Dreams” will also feature guest vocals from Beyonce, Blue Ivy Carter, Tove Lo, Martin and Paltrow's children and Noel Gallagher, plus a sample of President Obama's rendition of “Amazing Grace”. Lead single “Adventure of a Lifetime” has Coldplay fans abuzz over the album, rumoured to be the band's last, which will drop Dec. 4.
