It isn't a digital TBM book, only the A to Z listings, amended and updated.
It includes unissued songs recorded by groups that DIDN'T have an LP (otherwise, the ratings would require three times more work than it already does). So, no unished Beau Brummels, Remains, etc. Just unreleased "master tape only" tracks by the obscure combos.
In addition, songs that were shown as unavailable for a rating in both books, and songs that were only issued on compilation type LPs in the '60s, like the New York Ren-Vell Battle Of The Bands LP. That said, the mighty Traits "High On A Cloud" rocketed into the Top 1000, as it should be.
Target date for unveiling is summer or fall of this year.
