After finally hearing the original version and hearing the missing words, do you guys think that "This Ain't Livin" was written for (and to be performed by) Snoop Dogg????????? 2Pac mentions "it's Snoop Dogg, nigga Pac, would you ride with me?", "I disappear and reappear as The Doggfather", "as I step in blue", "To all my dogs out there raising hell".
I know songwriters do this all the time by recording a reference track.
