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.
That's how I tentatively "imitated" Aphex Twin and Autechre when I was a teenager using impulse tracker. Selecting random files as samples until I would find a section that sounded the way I wanted.
I think it's the sort of thing Master Boot Record should do
