This is a hard question for me to answer because I love a lot of Michael Jackson songs, but my two favorites are probably Is It Scary and Who Is It. Of the two, I think Who Is It is the better song. That means it’s probably my favorite.
The problem is that I don’t know whether or not my “favorite” automatically means it’s the one I think is the best. If it does, I second-guess my answer even more because he has songs I don’t necessarily think Who Is It is better than.
