Does anyone knows some content that it’s blocked in USA ?

Hello, as the title says I need some content , probabily songs are the best that have content ID blocked in USA , geo restriction.
usually I check everyday songs on but can't really find them and some say are blocked in usa but when upload on my test channel they are not.
so.. If you know something please let me know, if not please avoid this thread and sorry for wasting your time reading this :)
I just need it for a project :)
