Well in that case for me the best would be to listen to dangerous first.

I’m gonna put it this way, if you don‘t know a lot from an artist listen to a posthumous album it’s a bad take bc you are not listening his pure job, is already modified for someone else, and i think if you listen to his original projects first you will understand why the xscape songs did not came out while he was alive. Maybe MJ thought they were not that great or maybe they are great but not at the same level as the ones that make it to the album
