I made a completely sample free demo song for a friend to jam to and got stopped by the algorithm. I was referred to a song that was from a musical number with lots of chord and time changes. My sound was a single verse that was straight-ahead 4 chord rock. So while I wasn't hit with a takedown notice, I was prevented from posting until someone could listen to both songs (also it was really hard to listen to the song they quoted due to it's rarity).
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.
