Chet Baker was a leading jazz musician in the 1950s, playing trumpet and providing vocals. Baker died in 1988, yet he is about to add a new claim to fame as the lead plaintiff in possibly the largest copyright infringement case in Canadian history. His estate, which still owns the copyright in more than 50 of his works, is part of a massive class-action lawsuit that has been underway for the past year.

The infringer has effectively already admitted owing at least $50 million and the full claim could exceed $60 billion. If the dollars don't shock, the target of the lawsuit undoubtedly will: The defendants in the case are Warner Music Canada, Sony BMG Music Canada, EMI Music Canada, and Universal Music Canada, the four primary members of the Canadian Recording Industry Association.

These numbers may sound outrageous, yet they are based on the same rules that led the recording industry to claim a single file sharer is liable for millions in damages.
