Rock With You and Get On The Floor have just been mixed differently.
Bad has some of the trumpets taken out of later versions.
TWYMMF originally didnt have the adlib to fade.
IJCSLY has had the spoken intro removed.
Dirty Diana has been mixed differently and is a few seconds shorter.
Smooth Criminal doesnt have the heavy breathing at the beginning anymore. Plus there is a new bass slide towards the end of the track.
TDCAU has extra drum programming in it plus the obvious Jew & K*ke SFX added.
This Time Around has been reprogrammed to actually start at the beging of track 3 instead of at the end of track 2.
The original HIStory intro was a pre-recorded stock track. The reissued HIStory intro was an original recording which includes bells and is altogether more powerful than the original intro.
And now Unbreakable has a drum/bang sound in the first sec of the track.
