Earlier this week Chris Martin of Coldplay announced that Beyonce would appear on his new album ‘A Head Full of Dreams.’

Turns out Bey appears on more than one song and her fans will be surprised at her new sound…

Chris Martin tells London’s Magic Radio

“She sings on two tracks, yeah. Three, really. But she is just wonderful, as you know, and she was so sweet, and I said, ‘Is there any chance you would come and help us do some, you know, backing vocals?’ That’s how it started, ‘cause we were trying to keep it a secret, but she just sounds so great that I think we faded it up in the mix a bit.”

“And then on one song, ’Hymn For The Weekend,’ I said, ‘Could this be a bit more of a duet?” and we just — she was just so lovely to watch sing. She’s so good, it’s insane.”

“When she’s on the microphone in the studio, you can just tell that this is a person that can choose any color from the palette and do it perfectly, musically. She sounds a bit different, and she was very kind of humble. She didn’t really want, she didn’t ask for anything or say ‘I need my own bit here.’ She was so lovely.”
