dramacydal are on every version of runnin except eminems remix. the true original version of runnin from the police was supposed to be on thug life. 2pacalypse now was supposed to be a double album. friends was recorded for makaveli. ready 4 whatever, the original version of cradle 2 the grave, losin it, is it cool to fuck and others were meant to be on thug life at some point. strictly 4 my niggaz was a whole different album at first, troublesome 21. flex was cut from the album itself. as for all eyez on me, i dont know what songs or how many of them were cut but probably a lot. the one with faith evans being one i think. only one person can verify this and he is no longer with us.
you're going about it the wrong way though. try not to think of it as tracks being cut off albums because that can easily be mistaken. how many tracks do you think pac recorded for each album? im guessing a lot lol. a track actually being cut from an album that is done is a rare thing. 60 tracks being narrowed down to 15 that are used for an album, on the other hand, is more likely.
