To be honest I think some Loren's work for MJ now sounds a bit cartoony since we associate it with Bart Simpson but I kinda can see MJ liking the fun of 'Work That Body' before that. If it was remixed well however it could be an amazing track imo: very catchy and those 'verbs' in between are amazing!
In the recent leaks we see MJ beatboxing parts of 'Serious Effect' in the studio, so he must have liked that one too.
'Man in Black' sounds cool but seems to miss a lot: I have no idea if what we hear is a chorus, pre-chorus or lyrics lol. Anyway once this was the most anticipated demo among fans so maybe there is more out there..?
'Superfly Sister' has a bit of a dull instrumentation but the vocals are amazing and toward the end it does get pretty funky..
