Excuse me for being part of a small minority, but, on my mind, neither Axl nor any other artist should release all of the songs he/she has ever written. Even a musical genius like Michael Jackson left more than 200 unreleased songs behind, when he passed away. It's pretty much obvious that, even though there might be "three albums worth of songs", not all of them -if any- are decent or at least meet Axl's high standards. In addition, a riff is always far away from being a proper song. He might be waiting for the inspiration or the right time to make something good out of the material he's been left with. Or, more pessimistically, he might consider his material already outdated. In all honesty, I'd rather wait more than get to hear a CDII in the foreseeable future with songs like Scraped or Riad or songs talking about masturbation.
