I wasn't able to figure out the difference between the two versions on MySpleen, either. I have the BLAK0019 - KCCI version. It's got a station identification briefly overlaid on the animated segment, but it's just there for a couple of seconds. The quality was quite sufficient otherwise. For the wothless dreck that is the SWHS, of course. (Okay, I kind of like the Bea Arthur and Jefferson Starship numbers.) It's heavily padded with extras, some of which are still commercially available, and some of which shouldn't be available anywhere. Oddly enough, it seems to be missing Bentframe's Flash toons; seeing Jabba sing "O Holy Night" in Huttese would've truly completed the experience.
