Ah good point. Hadn't considered mods as a distro mechanism. I still have all the mods I made in the late 80s/90s - rendered them and uploaded to Soundcloud for the world to enjoy / laugh at ... a very resilient format!
Sometimes they are low bitrate mp3s, too, which I guess can work for some songs in the genre which deliberately low bitrate samples.
opus can do good audio even before transparency bitrates (without both the very annoying mp3 metallic ringing or ogg muffled sound)
