I think that be true for some of them, it not like they merch so much crap out of stuff because they like the designs, but i also can't really think of a band that has left more money on the table than GN'R. They would have made more money if they reunited sooner & sold more music if they promoted it. So it can't just be that alone.

Song wise I think the only thing of worth left over from thoses days that we need in actual decent quality is a version of Ain't Goin Down with vocals. I think Axl said himself they wanted to "put it all out". I find Mayhues claims about multiple AFD era songs left over unlikely. I suspect he mispoke and meant Chinese era songs

Where is Marc Canter? That guy seems to have vanished

Great Blues voice, would work really well.

Mike Clink is working on this. Wouldn't surprise me if Slash tries to get Izzy on it too in an attempt to build bridges

Free program called Spek, lets you know the true bit rate. It tells me that that track is under 64kbps which is not great. Say someone sends you a song that they claim is FLAC or 320kbps, it may have just been copied from a lower quality source. If you run it through this you can tell
