It's not even finished yet, but Coldplay's forthcoming seventh album already has a title.

The band are in the studio to record the follow-up to this year's 'Ghost Stories', released in May - and Chris Martin revealed last night on Zane Lowe's radio show that it will be called 'A Head Full of Dreams'.

"It's our seventh thing and the way we look at it is like the last Harry Potter book or something," he said. "Not to say there might not be another thing one day but this is the completion of something… It was great to go from Ghost Stories to go right back into the studio and now we're making things that sound different. I have to think of it as the final thing we're doing otherwise we wouldn't put everything into it. Then we will go on tour."
