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.
