But there’s a real problem with this solution.
Instead of placing the onus on the party making the copyright claim, it asks the person who posted the video to prove that what they posted belongs to them.
I think that, if you’re going to make a copyright claim against someone like this, you should also bear the responsibility of demonstrating exactly how that person has violated copyright, as well as the responsibility of demonstrating that you are indeed the copyright holder.
As it stands, the music publishers can use a flawed, inaccurate, scattergun approach, and just sit back and wait for the innocent party to prove his or her own innocence.
