Looking for the Vile Flesh song origins, I found this old post from 2006. Unsurprisingly, the links are dead, but the site is still on the Internet Archive (click on the broken image that goes to "download.html").
But the vilefleshmidi.zip file isn't. Did anybody happen to save it? I'd like to have these files in their original MIDI form (not converted to MUS), as well as know if they are given titles or any other metadata absent from their version in vile.wad.
