Listen to Coldplay on iHeartRadio

Coldplay fans are on the hunt for Chris Martin's handwritten lyrics. 

The British rockers hid envelopes containing the frontman's work from their upcoming album Ghost Stories in libraries around the world. 

They were appropriately been stashed away in nine different ghost story books, with one containing a special Golden Ticket.  The ticket will bring the lucky fan who finds it and a guest to Coldplay's upcoming concert at London's Royal Albert Hall on July 1st. 

The new album, meanwhile, is due out May 19th. Check out who found the lyrics!
