Hey! New here, and I realize this is an old topic, but that's my upload of those remixed tracks! I'm glad my YouTube channel "Ryan Jordan" can spread those versions of the Grey Daze songs even if I prefer the original mixes (and that the band hasn't tried getting them taken down yet, haha).
One other thing I noticed about the remixed version of B12 released as "B12_demo.1997.aiff" released onto streaming and the Japanese CD for The Phoenix is entirely lossy, and looks like it was pulled from the leak itself when I compare them with spectogram, not touched up or anything. So I'm wondering if the band themselves even has a master copy of that version anymore or if the leaked MP3s are all they have.
First picture from original leak, second is a FLAC file I purchased from Qobuz.
Similarly, although I don't know how this would even happen, the hidden track version of The Down Syndrome released onto Amends Stripped is also lossy sourced, despite easily being able to pull from an original CD copy. That one just seems lazy to me. I'm a really big fan of Grey Daze but things like these are just confusing to me. I pre-ordered the Wake Me & No Sun Today reissues and I'll be sure to look at those files too.
(If I'm extremely late to finding this out please let me know or redirect me to a better spot for it. I love GD but it's very difficult to find places to talk about them outside of their official Discord)
