This video blew up a few days ago on Youtube: https://www.youtube.com/watch?v=Mz14Ul-r63w The author shows how to sort of turn the tables on the copyright abusers by producing an original song (if you could call it that), distributing it through a distributor (1) and then using it in your own video to be able to claim your own video for a 50/50 revenue split with the abuser. Seems slightly related to this one as well. In the end stuff like this goes to show that Youtube's systems are a complete and utter joke, but since Youtube has zero competition, it won't change.
1: The creator used CD Baby, if you're going to do this, I recommend DistroKid, it is about a zillion times better than CD Baby. Even the CD Baby creator endorses DistroKid.
