Check my previous posts (in general) about many of the unreleased songs that you are asking information for.
'Shut Up And Dance' was meant for the 'Invincible' album, and it was allegedly planned as the lead single from the early, original version of that album.
Michael Durham Prince claims that he has that funky song in his laptop.
'Shut Up And Dance' is said to have Michael Jackson's vocals on it (at least, the chorus of it).
Also, author Joseph Vogel implies, in his 'Man In The Music' book, that most of the Bryan Loren tracks have vocals on them.
This seems to suggest that not only 'Verdict' has vocals, but also tracks like, 'Do Not Believe It', 'Seven Digits', etc, which were recorded at the Westlake Recording Studios (California) in the early 'Dangerous' album recording sessions.
“Shut Up and Dance” was never considered as the lead single. That would imply that it was developed enough to be on an early configuration of the album, which it wasn’t. I’d love to see a source.
Michael Prince co-wrote it, so he absolutely has copies (but he also has copies of almost everything he recorded/mixed for MJ).
There are two demos of “Shut Up and Dance”: one sung by co-writer Eric Kirkland and one by an unidentified female vocalist. Joe Vogel, Damien Shields, and Michael Prince have all stated that MJ never recorded it. Vogel insinuated that there may be some VERY preliminary scratch vocals, but not nearly enough to Frankenstein a finished song.
As for the Loren tracks, Vogel never “implies” that they’re mostly finished. They worked on around two dozen, but we’ve heard most of the “finished” ones already. Basically everything else is scratch vocals or instrumentals, as Loren himself confirmed during his Paris seminar in 2018.
If I’m not mistaken, “Verdict” is just an instrumental. “Don’t Believe It” and “Seven Digits” have scratch vocals. “Truth About Youth” has conflicting accounts. “Call It Off” and “All the Truth” are in the same layout as “To Satisfy You” — Loren sings the verses, MJ sings the choruses.
