Ok, I can hear a similarity in the songs. If you haven't checked this out yet, go to youtube and view the video that compares Coldplay's "Viva la Vida" to Joe Satriani's "If I could fly". First off, I don't think Coldplay listens to this guy at all, nor ever has for that matter. Secondly, the Satriani version is just a segment of one of his annoying, lengthy solos. Plus, Joe has all these dumb extra notes, bends, and tweaks to his song.
I think the court will decide the following:
Coldplay you are guilty of being music for jaded alternative radio fanatics and Satriani, dude, you just play creepy music that middle aged bar-going men think they can get laid for jamming along to.
You're both sentenced to LIFE as annoying musicians.
