Off the top of my head and to the best of my knowledge, releases that never were released on CD are: Mellow Man Ace-Mentirosa single, Esham's Erotic Poetry (Part #2), Spice 1-Strap On The Side (Maxi-Single?) and E-A-SKI - STRAIGHT BU$INE$$ (MAXI-SINGLE?). The Above The Rim and Murder Was The Case soundtracks, contain some bonus track/s that aren't on the CD versions. I never bothered listening to much of that Esham and don't really know if there is a difference from the first version, but I remember seeing someone say it was re-recorded. I might hold on to the Spice 1, but not sure yet and I've considered putting that Esham on ebay to see how much some crazy Juggalo may dish out for it or whatever.
