I've been making osu videos and uploading them to youtube. When I upload them some videos were copyrighted and I don't know how to not get copyrighted on my videos. I've been copyrighted 2 times already and I don't know if I should upload more till I figure out how to not get copyrighted. Is there any other way where I can't get copyrighted. Please help me out on how to not get copyrighted.
