Super messed up Youtube songs?

Youtube songs don't work for me if I try to play them in the search area. All the ones that are already on my playlist seem to work most of the time, but during search, it brings up the sorry-this-song-can't-be-played message and then switches to the Michael Jackson - I love you (Live with James Brown) video. And if I try to add it to my playlist before playing it, it just adds the same Michael Jackson video. This has been happening for about a week now. I DON'T EVEN LIKE MICHAEL JACKSON. WHAT IS THIS.
