This is a great example of how badly configured these systems are and how ultimately, they do more harm than good. It also brings up an interesting question. After a couple hundred years of recorded music, eventually everything will have some historical basis. If copyright law is to be enforced this harshly, then how do new works get created without hitting some automated censor firewall?

The elephant in the room, of course, is how strong copyright laws are. Unfortunately, Congress has shown little interest in reforming them.
