Based on the 1993 deposition, we can infer that Rolling the Dice was a home demo that never left Hayvenhurst, like several tracks from Prince’s “Piano and a Microphone 1983” (i.e. Cold Coffee and Cocaine). If this is the case, it’s likely that the reason it was left off of Thriller 40 was because it wasn’t up to the vocal par that the Estate requires to release a song, and not Quincy’s rejection, as Quincy would’ve had no say on it. All of the home demos are very rough scratch vocals, laying the groundwork. The reason we have the home demos we have is because they are from songs Michael either released or worked on in an actual studio (Behind the Mask). Something that never made it to a studio probably isn’t going to be released.
