Amaru are clueless. The only way a 2pac would sell if they put someone who knows the music in charge. Edi is retarded, and has too much influence.
A few JJ tracks would be good, but I'd make sure he didn't censor DR. It isn't Pac's beef, so don't involve him.
If I had creative influence, I'd keep a few of the hot tracks OG, get a few remixes by decent producers, who make music similar to the feel of the OG. I'd also give the album some promo. At least a fucking single. But at the end of the day, 2pac died a long time ago, and his legacy died with the last album. Amaru are steadily losing their fan base. Eminem didn't make it sell, and if he can't no-one can. Try making good music instead.
