According to US reports, british rockers Coldplay have denied the delaration about plagiarised music of an American band for their new album "Viva La Vida".

New York-based Creaky Boards claim that frontman Chris Martin was spotted attending one of their gigs and his band went on to use one of their melodies for a track on their latest LP, informs Showbizspy magazine.

Songwriter Andrew Hoepfner said: "We were flattered when we thought we saw Chris Martin in the crowd that night. He seemed pretty into it. Maybe too into it.

"The crazy thing is that my song is actually called 'The Songs I Didn't Write'."

But a spokesman for Coldplay has dismissed the claims, saying, "Viva La Vida was written and demoed in March 2007, which is more than six months before this band claim Chris went to see them!

"We totally refute their claims."

Martin has also denied attending the Creaky Boards gig - claiming he was in London at the time.
