My favorites are Billie Jean, The Way You Make Me Feel, Beat It, Thriller, Don't Stop Til You Get Enough, Black or White, Scream, Earth Song, Leave Me Alone, Smooth Criminal, and Bad.
One of my favorite Michael Jackson songs is "Got to be There." The instrumental intro triggers so much emotion. Then, Michael's angelic voice pulls at your heart strings. "Rock With You" is another of my favorites. It's such a feel good song with it's seventies vibe. Whenever I hear it I think of my youth roller skating, bike riding, etc.
My alltime favorite Michael Jackson song is the one and only "Earth Song". Songs I also like are "Heal the World", "Black or White" and the very song that made me aware of the singer in my childhood days, "Thriller".

I would say that I have two favorite songs by Micheal Jackson. The first is "Beat It" because Weird Al happened to do a music video parody of it and since Micheal Jackson liked him he allowed him to use the same set. The second one I like due to the music video is "Thriller."
