Back in the day, we actually had semi-decent stuff coming out. While most OGs were better than the remixed songs, only a few of them were actually horrible and complete trash.
Out of the Amaru-released Pac songs:
Unconditional Love is basically the best quality OG that Amaru could attain
Troublesome '96 is pretty fucking close to the OG
Letter to the President is pretty fucking close to the OG (minus different Outlawz verses)
Teardrops and Closed Caskets is pretty fucking close to the OG (minus the "...in this world" line removed from the chorus)
Good Life is pretty fucking close to the OG (minus different E.D.I. verse)
Fuckin wit the Wrong Nigga is basically the OG
Runnin on E is pretty close to the OG
Releases in OG format (or at least close enough to where it's still basically the same thing) HAVE happened, though less frequently in recent years.
People were praising Eminem's beats? I don't remember that. I'm sure there might've been a few people who liked Ghost, but I don't believe that the majority was happy with the overall Eminem vibe of the Resurrection soundtrack songs. And Pac fans have every right to complain, whether or not it's Eminem. I understand your argument about beats, but the difference with E.D.I. producing (even though he was very close to Pac) was that he never really produced anything for Pac while he was alive... at least not many songs, if any at all. E.D.I. doing beats is far different from Daz, Johnny "J", QDIII or even Dre doing remixes, all of whom supplied music for Pac in the studio in the past.
People can complain about the album cover if they want. While I'm sure Amaru was going for a simple yet elegant cover (hence the plain white background behind Pac in a tuxedo), it looks too basic. The bootleggers from 1997 made far better covers than this. While album covers should never be the selling points of music, they could've perhaps spent another 10 minutes creating a cover. I'm very grateful about the music as well and I'll buy it no matter how bad the cover looks or who the producers are, but as a fan, I'm disappointed that the best-selling rapper of all time who was also one of the greatest overall can't get a decent album cover that utilized Photoshop or Illustrator rather than Mario Paint.
