I Thanks For The Tip Bronic! and Thanks 2 Psyclon! I like Deutsch Elektronische Musik!
I am not completely done with my list, I am at page 60. I might add more electronic / synthy stuff later :D
But the vast majority seem to be jazz and swing disks usually from the "usual culprits".
They appear to be all in MP3 format.
Funny. As someone who takes internet security seriously my main concern would be the country the site appears to be based in.
I fully understand your concerns as I am also concerned, but I turned down my paranoia into healthy distrust. The servers are CloudFlare ones (jill.ns.cloudflare.com and todd.ns.cloudflare.com to be precise), the files themselves clean. Yes, there is Yandex involved (Russian Google sort of with cloud storage, mail, et cetera) and probably some files come from there, but even then, I highly doubt my computer to turn into a Putin bot spammer by downloading a clean MP3 and a bunch of truncated cookies. Apart from PrivacyBadger and NoScript (which both actually alert me to much stuff that I whitelisted manually), there is not much you can do about it. There is not much of a difference if I get spied on by the USA, Russia or China. I mean, this is the internet - interconnected network. We all will meet people from super powers like China (like ChinYinZi), Americans, Russians et cetera. By that logic, I should never receive any files and turn off my Microsoft Windows-operated PC.
In general that is like COVID - you meet sick people, vaccinated people, vaccinated sick or unvaccinated healthy people. Having an EU certificate of my 3 Moderna shots didn't make me less infectious; the alternative would be to stay at home - or, to go back, pull the internet plug. I mean this in a neutral tone by the way, not in any way condescending. I just opened Mediafire and 7 Javascripts and 3 Trackers on that website, 4 of them belong to Google - an US company knowing to spy into people's lives. . . . .
EDIT: Just as I posted this, my browser waited for this:

What is that service, what does it do? Do I want it? Nope. Do I have a change? Nope either..
When looking up, it's this - and immediately wants Scripts to be executed, but aforementioned NoScript stopped it:

So that above was connecting to my session just by editing a thread on LMT. Makes you think...
Alternatively, I would honestly suggest you a sandbox VM or something. There you can put these files literally into quarantine and only fiddle out the audio files onto your real system after you checked them thoroughly. I often enter dubious websites because Google got me into some slavik forums, but these happen to have LP recordings found in their attics from behind the Iron Curtain, but actually is a clean forum. It just "feels" dubious, and often less dubious than Google and Amazon spy networks form the USA. And DuckDuckGo unfortunately does not yield the same obscure results, and I am using Youtube (and thus Google) anyways, so the ship has sailed there :/
