I get what youâre saying but I disagree with this and I donât even think this is a true definition of the word âdemoâ in musical terms. Just because a song was withheld from a release doesnât necessarily mean itâs a demo. Itâs a fuzzy line, itâs not clear-cut like that. Imo Someone put your hand out, Xscape, Is It Scary cannot be described as demos even if they missed their spots on their intended albums.
But for the sake of posthumous albums I think the best strategy would be to call them demos.
