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.

Chris Martin has said: “We’re definitely good, but I don’t think you can say we’re that original. I regard us as being incredibly good plagiarists.” I bet he wishes he hadn’t said that now…

Though what really caught my attention with all this is yet another use for YouTube. A video titled “Did Coldplay copy Joe Satriani? ” was uploaded to YouTube comparing both songs and asking people to comment, using YouTube as a destination for generating discussions based on a hypothesis presented in a video format. The video is less than a week old and has over 1.5 million views and almost 12,000 comments.

With that said, I wish YouTube had a better comment management and filtering, allow to search on comments, filter by date, rating, display only your friends’ comments, etc …

So we’ve seen YouTube being used for entertainment, news, learning, gaming, advertising, and discussions… I can see YouTube using Google Friend Connect or if Google is smart, even Facebook Connect to gain a few new million users
