The RIAA have instructed YouTube to pull over 100 guitar tutorial videos by a guy called John Sandercoe, because one of them features a "how-to" of a Rolling Stones song.
This is what's wrong with modern copyright law. Sandercoe, a guitar teacher from London, posts himself playing a song as an instructional tool, and the record industry tries to sue him. He wasn't distributing the actual song (not even as backing for his own performance!), just educating people on how to play it for themselves.
YouTube, and by extension Google, should be ashamed of themselves for giving in to this.
