I remember reading that post but I didn't initially recognise you so apologies for that.I made a huge post about that. The 2003 surround sound mix of their second album has a TON of errors on its release. Its timbre basically forgoes the Wall of Sound style in translating it to surround sound, so it's an incredibly interesting listen for that alone. With the errors fixed, I think it's still a rather lame surround sound mix (albeit better than with the errors), and it honestly is more interesting for how it sounds flattened to stereo.
Here is that post, btw: https://www.quadraphonicquad.com/forums/threads/fixing-oasiss-morning-glory-in-5-1.33250/
Btw did you get sick of that album from constantly having to listen it for the mix? Lol
