Actually I had a thought about this set list yesterday.
In the unlikely event that it is real of course.....
You'll notice that there's no negative or sad songs in this list, perhaps indicating a desire on Jackson's part to present a wholly positive concert experience.
Notable omissions?
Earth Song - Whilst an incredible piece of work, it is essentially a bewailing damnation of the human races treatment of the world. In contrast to Heal The World, it doesn't offer any hope or solutions.
Stranger in Moscow - 'I'm in Moscow, I feel lonely, I feel belittled'. Nothing positive here, although again the music is beautiful.
She's Out of My Life - Title says it all.
Scream/They Don't Care About Us - Both angry songs with no solutions.
Having said that, it begs the question why Black or White isn't there.
