Joe Satriani sues Coldplay
Grammy nominees Coldplay have been sued by rock guitarist Joe Satriani, who claims the band's song "Viva La Vida" uses one of his riffs.
In court papers filed in Los Angeles last week, he said the song used "substantial original portions" of his 2004 instrumental "If I Could Fly."
Satriani, 52, wants a jury trial and is seeking damages and "any and all profits" for the alleged plagiarism.
Coldplay are shortlisted for seven Grammys, including song of the year.
"Viva La Vida" is credited to the band's four members -- singer Chris Martin, bass player Guy Berryman, guitarist Johnny Buckland and drummer Will Champion.
The song's title was inspired by Mexican artist Frida Kahlo.
It appeared on the album "Viva La Vida or Death and All His Friends," which was released in June and went to number one in 36 countries, and was also one of their hit singles.
Satriani's track appears on his album "Is There Love in Space?"
