How this Mac Dre+Snoop track come about?

In get stupid, im pretty sure he said "doctor dreg did it"? As in Dreagan, Ronald Dreagan. In the Gift dvd interview, he said he hasnt worked with Dr. Dre yet because he hasnt reached that plateau in his career. In that interview he looked very similar to how he looked right before he passed. As for the Snoop song, it sounds like Playboy W bought a Snoop verse. He also bought at least 3 Dre verses. One being said verse, and the other two being "State of the Art" and "Secret Fantasies aka Trill Shit"

Slightly off topic, but I got a homie who's bro is a producer for the SCC and other Los Angeles artists... he's also real cool with Spice 1 and Snoop, so he got hella rare unreleased songs by em that aint leaked... my homie say he heard an unleaked song with Snoop and Coolio.

I dont think so. Im pretty sure Playboy W just used two different beats for those verses. I have heard both versions and both have Playboy W on them. They just cut his verse off for the All Star Tribute album. Im sure him and Dre worked together in the studio because Dre did 3 verses for him. As for snoops verse, he more than likely bought it and thought it would be a good idea to put dre and snoop on a song to boost sales. If you listen closely theres no chemistry between dre and snoop and they both just spit generic verses, if that makes sense.
