In my experience, there has always been a great reason for leaving unreleased/different version tracks off of albums when they are originally recorded. That reason being: those tracks suck! They weren't considered good enough or fit well enough into the original recording sessions for a release, so chances are they're not worth hearing.

I recently bought both of the Genesis Archive box sets and listened to all of the first one. I was pretty happy I picked it up cheap, because it's not altogether great stuff. It's nice to have some live stuff that doesn't appear on the other live Genesis albums, but the 4th disc of unreleased demos and singles was pretty much crap, IMO.

I'd rather have an original CD of a recording instead of a re-issue with bonus tracks that don't fit with the rest of the album and sound like crap. If a band wants to release a collection of b-sides and rare live stuff, I might buy it. But I'll never fork over money to replace a CD for the same CD with crap tacked onto it. I still have cassettes I need to replace with CD's, for cryin' out loud.

Chances are, there will never be a release from a band made up solely of unreleased demos of songs that already appear on other albums. They just wouldn't sell, except to rabid fans and audiophiles (but why would either wish to hear an inferior version?). I don't really have any advice for you, Yesspaz, since you are excited about the bonus tracks and are probably going to by the re-releases regardless of my or anyone else's post. I just wanted to discuss my opinions about the crappy quality of most bonus tracks. It's just not worth it, IMO.
