I uploaded a brand new song onto youtube right after it was released two days ago and I was the first person on all of youtube to upload the song. Then within the next hour there were about 100 other people who uploaded the song. It was a long anticipated song and the people who are ranked as "New" right now have gotten 500k views in 2 days. Both of whom I believe stole the video I made. I don't care that they actually stole the video from me. But its the fact that if I do mark them as copyright, it will give me thousands of more views and potentially rank me first or a lot better. Heres my question: Has anyone marked someone else's video as copyright? What if I mark them as copyright for using my video I created, but the music on the video is not mine? Is there any legal issues if I do this?
