Drone On - resurrecting this thread because I just picked up Vols. 5-8 recently (still listening to Vol. 5) and had no idea these were pressed on CDRs. And yeah, the packaging is awesome but what's the deal with CDRs for these!? At least they do not sell for a whole lot online but still, kind of a bummer on that. I do have Vols 3 & 4 (on real CD) and I want to pick up Vols 1 & 2 and 9-12, but may skip 9-12... of course the completist in me may not be able to handle it. Speaking of which, any comments on 9-12?
