Coldplay frontman Chris Martin revealed Thursday that the band is at work on their seventh studio album, and it will likely be their last. Celebrating the band’s Ghost Stories track “Magic” being named the “hottest record of the year,” Martin said on BBC Radio 1’s Zane Lowe’s show that the set is tentatively called “A Head Full of Dreams.” Martin said, “It’s our seventh thing, and the way we look at it — it’s like the last Harry Potter book or something like that. Not to say that there might not be another thing one day, but this is the completion of something.”
