From Techdirt: Guitar virtuoso Joe Satriani has sued Coldplay for copyright infringement over claims that their hit single, Viva La Vida, used "substantial original portions" of his song If I Could Fly from 2004, seeking damages for "any and all profits." The lawsuit has been filed in Los Angeles federal court. Call me a skeptic, but it was just back in June when we wrote about a band called Creaky Boards making a similar claim. The difference is that the Creaky Boards didn't sue. They made a cheeky video and used the opportunity to get some attention (also, later retracting the statement after Coldplay refuted it). However, one notable difference here is that Coldplay was very unlikely to have heard the Creaky Boards song, while Joe Satriani is well known, especially among guitarists. When you listen to this clip, the melodies are certainly very similar. Compare the two songs here. What do you think?
