Got an advanced copy of this album. It's real nice and something LP/Jay-Z fans should give a listen to. I love a good collaboration and you know these guys are doing it for the fans and not for the cash. The best track would have to be "99 Problems / Points of Authority & One Step Closer."

Check it out. The White Album + The Black Album = The Grey Album. You'll love it.
