I have some popular YouTube videos, where I've used songs that I don't have the legal right to use. This of course has disabled the monetizing for some of my videos, which doesn't really bother me. I don't have to earn money from my videos. What I feel is odd that when I look at the copyright claim, YouTube says that the copyright owner is able to turn on advertising on my videos. Does this mean that both me and the owner of the music split the money, or does everything go to the owner of the music?
