The original configuration of Thriller (according to the book “For The Record”) was:
1. Wanna Be Startin’ Somethin’ / 2. Hot Street / 3. The Girl Is Mine / 4. Thriller
5. Billie Jean / 6. She's Trouble / 7. Nightline / 8. Carousel / 9. The Lady In My Life.
So before anything, 2 of the next 3 songs on CD2 really should be Hot Street & Nightline, to join the already added Carousel & She's Trouble. I'd also like Starlight to join them on Disc 2.
To respect the original intention for the album, it would have been nice if the full length original uncut versions of Wanna be Startin Somethin', Billie Jean, & The Lady In My Life were also included on the physical release. Maybe as extra tracks on CD1 along with The Girl Is Mine (solo demo), Thriller (with its 3rd VP Rap still in place) and the Baby Be Mine demo.
My guess though is the final 3 songs will probably be something like
Can't Get Out Of The Rain / Slapstick demo (instead of Hot Street) / Starlight (if we're lucky).
I'm also starting to wonder whether there are more finalised versions of songs such as She's Trouble, Got The Hots, Sunset Driver & Behind The Mask, and whether these songs and possibly others, had any finalised Quincy Jones input which he's not allowing to be released. If so, I do think such tracks, along with Hot Street & Nightline are being held back for a future release, or Thriller 50.
