After having a few days to really dig into both versions of the song it's 50/50 for me too, I think. I like how prominent the piano is in the McClain version, and also like the guitar riffs during the chorus and love the instrumental bridge, but I feel the bass and especially the percussion leaves a lot to be desired in terms of mastering and bring the overall quality of the production down.
The production on the JT version is a lot cleaner, with a strong bass-line and strings and much crisper percussion / snare, but I'm not a big fan of the bridge and in particular the Workin'... sampling, and kind of miss the prominent piano and guitar riffs. What happens after the bridge though, is much stronger than what McClain did IMO, especially the transition into the final chorus at 3:16.
So yeah, maybe not so 50/50 after all -- I guess I'm leaning towards the JT version, mainly due to the "muddy" sound of the production on the McClain version.
The Billboard article has me wondering though... If Reid and his team had this rule where they'd only use songs that had completed vocals *and* of which the vocals were recorded multiple times by MJ, then why did LNFSG make the cut in the first place? I don't mind having these versions and it's a great song (I love the demo) but clearly having only the one demo -- which doesn't have a bridge -- with vocals, piano, claps and finger snaps all on one track was a bit of a handicap here. Again, I'm happy with these versions and I'm very glad to see how well the song is doing, but it's maybe not the best representation of MJ's capabilities and what he left behind in terms of unreleased work? Did Reid & Co. just love the song so much that they simply *had* to include it, or did McClain push for it because it was kind of his baby? It's just a bit puzzling to me... I can't wait for the rest of the album though -- I think minds are gonna be blown when STTR, BG, APWNN, DYKWYCA and XSCAPE hit the airwaves
