You already named 2 of them that similar to Youtube.
Correct me: so actually you’re looking for a video sharing site where you don’t get Copyright notice of sharing someone’s else music and videos? how come your videos then if they are getting copyright notice?
Is it for real? I’m amazed by seeing these kinds of ideas you guys release here. lol
And hopefully, you’re looking for video sharing sites like Youtube that shouldn’t stop you from uploading copyrighted music and videos? am I right?

Try them, if they can give you a room to use copyrighted content, if they do you’re good if they don’t then the answer is, Stop using copyrighted content, find out copyright free music under youtube playlist and use them anywhere. and you can’t stop copyright on copyrighted songs or music unless you mute them if you do it’s a waste. so better Google search for copyright-free music if the Youtube playlist doesn’t suit your needs.
