I was clearly skeptical at first; after all, who wouldn't sue a major band just to get some Benjamins. But after hearing the two songs played side-by-side, I'm beginning to take Satriani's side.
You decide for yourself, and let me know what you think.
***Update***
Speaking of copyright infringements, EMI had Youtube pull all the Coldplay vs. Satriani. so, best I can do is post separate versions of Coldplay's "Viva la Vida" and Satriani's "If I Could Fly."
Viva La Vida
If I Could Fly (Go to 0:50)
***Update***:
I've heard a lot about this other video, so I thought I'd throw it up here. Hope this assists with the "Is Coldplay Copying Others Work?" discussion.
