It is not because we never heard of the song “dream away” that suddenly there is a ton more music in the vaults. The Estate’s claim that the vaults are almost dried up still stands as they had this song shortlisted for Xscape in 2014. So the fact remains there might only be a dozen or so tracks left for release.
If you take Xscape’s 8 tracks it leaves 16 tracks. You can be sure among those were nite line, hot street, dream away, Chicago 1945, can’t get your weight off of me, hot fun, who do you know, what a lovely way to go, she’s trouble.
This leaves 7 unknown titles.
