I don't believe that at all. If this was true, then why Ghost did not address this earlier when Action/Meyhem dropped it 14 years ago? I could be wrong but this sounds like cap since Ghost got caught sample stealing. Didn't Ghost do that same shyt with 9 Milli Bros?
Ghost was passed the Metal Fingers beat CDs being unaware it was the same person as MF DOOM (or Zev Love X who Ghost knew from KMD). He just thought it was a producer named "Metal Fingers." Once he wanted to use some beats for Fishscale and beyond, they connected and he bought up beats he wanted to use without knowing or caring about DOOM already using some of those instrumentals for some of his other released projects. To Ghost, it was just working off producer's beat tapes like usual.
Also, with that example and that MF DOOM's run didn't cross Ghost's radar and he knew him more as the KMD member, that should clue you in to how little Ghost was checking underground rap and how a song off a 2011 Meyhem Lauryn album would also miss him.
around 13:00 he talks about having the Metaphysics beat held
same producer for a Theodore Unit posse cut w/ J-Love giving an RIP tribute at the beginning
Silly ass shyt to say someone's lying about having a beat stashed when there's other examples on this album of beats he's held for over a decade. Especially with J-Love probably being the one to pass them both the beat being Ghost's main mixtape guy and putting Mehyem on at the same time.
Be better.
