Youtube Music doesn’t just serve the audio from a video.

Yes it does. You don't even need to take my word for it. Look up any song by any artist and find their official video for that song. Take this one as an example: https://youtu.be/kPa7bsKwL-c

Analyze it with yt-dlp or something similar;

140 m4a   audio only      2 │    3.90MiB   129k https │ audio only           mp4a.40.2  129k 44k medium, m4a_dash

YouTube already has access to the audio for that song without any additional effort because of how YouTube works. I'm sure publishers can provide higher quality audio, up to 256Kbps but that option isn't even enabled for users by default. By default you're listening to "normal" audio or 130Kbps: https://i.xno.dev/Ow2eC.png

The reason why YouTube Music works is because they already have access to a huge library of music through music videos and the like. They save a ton of time and money by doing things this way and it makes perfect sense that they do...

As I said, some of the music is just the audio of a video, but they also get a lot of releases directly from the publishers. They are both on YT Music and the difference in quality in between them is noticeable.

I have my audio quality set to high in that options menu btw.
