This has been making the rounds over the internet, so I figured I'd see what you guys thought. Basically, guitarist Joe Satriani is suing Coldplay for copying parts of Viva La Vida from his 2004 song "If I Could Fly". At first, I thought it was just some petty this, but I saw this youtube video and it is fairly convincing: http://www.youtube.com/watch?v=1ofFw9DKu_I To me it seems pretty evident that it is copying, but at the same time I recognize the impossibility of every song being completely original. Still, the same tempo and melody? Thoughts?
