If you like this sort of thing, I highly recommend checking out C. Allen’s work. The visuals and music are both really impressive, in my opinion the best out there: https://youtu.be/OP7sTQQ0Blw
The Oscilloscope Music scene has really come a long way! I love the aesthetic and that got me started on a project to convert an old portable CRT TV into an oscilloscope. There's something really satisfying knowing that the visuals directly mirror the sound. Getting something visually pleasing while still sounding musical is a really interesting challenge. Hansi Raber from oscilloscopemusic.com even wrote his own software for that purpose: https://oscilloscopemusic.com/software/oscistudio/
TFA is not putting music on an oscilloscope. Some of it is actually plotting frequency vs time in the video, so it's nice demo stuff but not true oscilloscope music.
Long ago I did like you and converted an CRT TV to accept audio on the deflection coils (left, right -> X,Y). I can highly recommend 2 particular songs for that setup:
1) Cathedral by VanHalen
2) Lunatic Fringe by Red Rider
By all means use a CD if you can rather than MP3 - I'm not sure how degraded the MP3 would be so maybe it's fine.
>> because surely you're not disputing the oscilloscope part of it
Yes, I'm disputing the oscilloscope part of it. An oscilloscope does not plot pitch vs time. You could devise circuitry to do something like that.
Having plugged audio directly into an oscilloscope, I can say that's not how it works. Well, not all of it. The into seemed more like it might actually be left/right audio into a scope, but the other parts did not.
You're right, it doesn't, and that's not what's happening here. It uses the X/Y deflection mode of the oscilloscope, plotting left channel vs right channel.
If you don't believe it, play it on an oscilloscope yourself. (I have!)

i'd suggest you do it again before making baseless accusations. they provide you the ability to download the audio. they even provide a bit of software to drive lasers with the data.
as a follow up to my own post. I couldn't remember the video, but the YT algo found it for me[0]. Smarter Every Day did a video with the same people from TFA that shows exactly how they do these. I can't find any better evidence to show your "thoughts" being totally baseless.
