My favourite is definitely "Much Too Soon." I first heard it like 1 1/2 months ago, and I fell in absolute love with it. But if I had to choose a second favourite it would be "Monster", and "Keep Your Head Up."
Honestly, I like the Ultimate Collection version of The Way You Love Me more than the Michael version. But my most favourites on Michael are Hold My Hand, Hollywood Tonight, and (I Can't Make It) Another Day.
