Ahhh finally, some numbers to work with 
OK here we go...
Re: Whitney Houston
Do you have 923R or 923N? Easiest way to tell, is to look for the NoNoise logo. If it isn't present, you've got a GDR that has been discontinued and replaced with a GDN. Let me know what you have.
Re: Chicago
GoldDisc 226 is the one that would match the 45 RPM single, "if" you are timing it until the song fades beyond useable level. In that case it goes to 2:46, even though the indexing code is positioned at 2:40. I'd trash 431 if I had it, unless I wanted the 7:00+ minute version of that song, which is the last track on the disc. 431 is a GDR. On your copy of 226, where does it momentarily switch to mono?
Re: Huey Lewis
You have what appears to be a GDR pressing of disc 149. The GDN version has the indexing code at 3:43, with full fade out at 3:53. Does your copy of 149 have the NoNoise logo? If not, it's most likely a GDR pressing.
Re: Stevie Nicks
GD121v1 more likely means GD1, the first generation of that disc. Can you describe the difference in the vocal and mix? I have 121N here, and I have another copy of the song on a Time Life CD. The versions are different
Re: Stevie Wonder
I don't have any knowledge of that one's release history (or lack thereof), so I have no comment.
Yes I know in this case, I am playing devil's advocate with regard to "timing geeks". However this is a more realistic approach because we are dealing with actual TM disc numbers now.
I've seen a few posts over on that forum where someone says "my copy of TM Century's disc has..." but they don't give the disc and generation number. Without that information, it's not worth the effort.
