I can't listen to them right now but from what I remember, Fall In Love is an out of tune mess that doesn't sound anything like Michael. Ready To Win... I don't know where to start with this one. It reminds me of this:
http://www.youtube.com/watch?v=X-7taGcm8lg - An impersonator singing over the Keep The Faith instrumental with new lyrics (in this case, to create a tribute song). Are we supposed to believe Michael played the On The Line instrumental and started singing new lyrics to create a new song? I can't remember the rest of them right now I'll post my opinion of them later.
Do you think it is Michael's voice? If so, do you find anything strange about it?
