I appreciate you sharing these, but I researched how CD rips work and these aren’t true CD rips. A real audio CD contains only the audio tracks. It won’t include extra files like text documents or code, it won’t have track names, and it won’t contain metadata because audio CDs don’t store that information. If anyone else has the CD collection, please rip them a share it.
I may live to regret this but.......
It is clear from your post and the fact that you had to research how a CD works that you are new to all of this. The audio files we extract from an Audio CD usually have a generic name which does not describe what it contains. On my Apple Mac they appear, for example, as "01 Audio Track.aiff". Obviously it would be difficult to identify individual tracks in a collection if they all contained the same name. So, during the ripping process it is usual to add more information in the form of Metadata to each of the ripped files so they can be more easily identified. This is called tagging. It is also at this stage that one decides what format to save the file in; WAV, FLAC, MP3 etc.
Hence none of the CD rips you will find shared on this forum, or perhaps anywhere on the Internet, will be the raw data taken directly from a CD. But that doesn't mean they are not true representations of the audio data contained on the CD. So, unless there is someone out there whose collection consists of just the original files from an Audio CD I'm afraid your quest is like searching for gold at the end of a rainbow.
Oh, and incidentally whilst a CD does not contain Metadata there is an extension of what is called the Red Book standard (the standard by which CDs are manufactured) which is called CD-Text. This can contain information including the title, performer, composer and genre of a track. Most modern CD and DVD players are capable of displaying this information while the disc is playing.
