i thought u cant c me was orginally a dre an cube song than became a dpg song

I bet a lot of the songs were originally scheduled for other albums, perhaps bar the Johnny J tracks. Think about it - given how long it took Death Row to get around to dropping an album, AEOM hit the streets AMAZINGLY quickly. Apart from Pac'w work ethic and Johny J's matching that, the only way I can see them having done it would be to use pre-done tracks.
