what do you mean by that?
they could also keep the audio up, and take all the monetization of that video.When you use copyrighted music your video will either be a) monitored by the company that owns the song or the more probable b) YouTube will completely remove the audio to the video.
Someone correct me if I'm wrong here but that's the only two I've seen happen.
