Mexico's Search & Destroy has posted an audio interview with guitarist Joe Satriani. You can listen to Joe Satriani talking about Coldplay's Viva La Vida during his podcast here (the Coldplay clip starts around the 13m20s mark).
According to The Pulse, Coldplay's record label, Capitol/EMI, had forced YouTube to remove a video clip that mashes up the band's song "Viva La Vida" with Joe Satriani's "If I Could Fly". Satriani recently sued Coldplay, claiming that the British quartet plagiarized his 2004 tune for their 2008 hit. The video, which plays a segment of each song separately before layering them together, has been widely accessed by music fans to compare the tracks and debate whether Satriani's claim could have merit.
Satriani filed a copyright infringement suit in Los Angeles on December 4, one day after Coldplay was nominated for seven Grammy Awards, including record of the year for "Viva La Vida". He is seeking a jury trial, damages and "any and all profits" attributable to the alleged copyright infringement.
