This goes under the old news/news to me category.
Apparently back in 2002, English composer Mike Batt had action taken against him by the John Cage Trust for his song "A One Minute Silence." He was sued for plagiarism of John Cage's completely silent piece "4'33"" and ended up settling out of court for 6 figures.
C'mon really?
How can you sue over silence? And more importantly even if you could, why in the hell would you??? Maybe if Mike Batt's track would have also been 4'33" there would have been a little bit more of a basis to go on but still, consider it an homage and call it a day.
I do want to clarify, it was the Trust of John Cage that was taking action not the the late/great John Cage himself. He can still be respected.
Also, Mike Batt himself is hilarious. These are some choice quotes from the CNN article:

"Has the world gone mad? I'm prepared to do time rather than pay out. We are talking as much as £100,000 in copyright."

"Mine is a much better silent piece. I have been able to say in one minute what Cage could only say in four minutes and 33 seconds."

"A One Minute Silence" has now been released as part of a double A-side single." I really kind of want one.
