It’s worth getting the Quake shareware disc for the NIN soundtrack. Official track names are now available following the vinyl release a few years ago. This is the only CD release of the soundtrack. Just don’t forget to skip track 1.

There is very slightly more to it than just the mixed-mode sessions: the audio tracks on the Quake CD were mastered with pre-emphasis, so your ripper or player needs to apply corresponding de-emphasis EQ in order for them to sound correct. 1996 was actually a strangely late year to find any CD mastered with pre-emph; it was mostly an '80s thing: https://www.studio-nibble.com/cd/index.php?title=Pre-emphasi...
On top of being a technique that had fallen out of common use by that time, Quake has the pre-emphasis metadata flagged in the subcodes but not flagged in the TOC, so some software players/rippers like (annoyingly) Exact Audio Copy won't heed it: https://wiki.hydrogenaudio.org/index.php?title=Comparison_of...
Here's a side-by-side comparison — my EAC rip of my MacSoft version of Quake (left) alongside the output of `sox_ng deemph` for the same file (right): https://i.ibb.co/9m18CSsk/Emi-2026-08-17-18-52-48.png
And if you're curious, here's the pre-emphasis subcode channel Q flag and pre-emphasis frequency response as described in the Red Book standard, and sox_ng's code for undoing it:

Although if someone has been unknowingly listening to the pre-emphasized tracks for thirty years, maybe the ‘incorrect’ one is what sounds right to them? :)
IIRC, it's actually debatable if the pre-emphasis flag is supposed to be set. I don't remember the exact details anymore, but I think it was discovered that there multiple releases with bit-identical audio tracks, but some of them have the flag set while others don't. They can't both be correct, because the audio data should've changed if the emphasis was removed.
Make sure that it isn't a case of the software you're using to inspect the disc intentionally looking the other way with regard to that flag.

I learned that this is an intentional deficiency in EAC: https://forums.stevehoffman.tv/threads/eac-not-detecting-pre...
> For a short while, up to version 0.95b3 [in 2004], Exact Audio Copy had a manual function to actually scan the audio area of the disc also [talking about subcode channel Q versus the TOC] to find if tracks used pre-emphasis. This was removed due to some perceived legal threat. Now, basically, a standards-compliant disc that doesn't use the TOC kludge won't show "pre-emphasis"
And sure enough, the Red Book standard mentions usage of the other three flag bits alongside the pre-emphasis flag: https://audio-union.com/wp-content/uploads/2023/02/Red-Book-...
The adjacent bit is “copy prohibited” versus “copy permitted”, which is not a piece of metadata I knew Compact Disc had. Makes a lot more sense why EAC would remove that feature in the legal climate of the P2P era, because to look for one flag also must look for the other, and this way it's out of sight and out of mind and Gee Your Honor We Didn't Know You Couldn't Do That if someone uses EAC to rip a “copy prohibited” disc. I wish I could get this feature back in 2026 though :p

The data track never sounds very good. A little too industrial for my tastes.
Now I'm curious if it's possible to make a data track that has at least some resemblance to actual music. That could be an interesting challenge if it can't obviously be ruled out.
In each sector 2048 of the data bits are just bits, but each data sector also includes 12 bytes of sync, 4 bytes of metadata and 288 bytes of ECC that are not really controllable (if you want the disc to be readable). Then there’s the ISO 9660 on top that will impact the first few sectors. If you have a single file (say a zip/tarball/rar, image) you could limit that. Assuming you could mask the noise from the ECC at 75hz it might be possible.
Sounds like the sort of thing Aphex Twin would do.

Honestly that'd probably appeal to Reznor's aesthetic.
Mind that every Quake release includes the same soundtrack, it's not just the shareware version ;)
There's millions of such CDs in the wild, both shareware and fully purchased copies.
Oops, I can see how that reads like only the shareware version is this way. It’s often cheaper if you’re just going for the music.
I remember I had the CD but rarely used it because having to pop in the CD just to play the game was annoying. So, I mostly played it without the sound track. Also, I never was that much into nine inch nails. Just not my genre. But my memory of the game is that it was fine without music.
NIN and iD (re-?)released a vinyl record set for the 30th anniversary a couple weeks ago.
