Shane (dust11) and Alexey Torgashin sent me a link to a web archive to a guy who pulled the files off of a backup:

http://ducker.org/~jrodman/kmods/mods/artists/Necros/ http://ducker.org/~jrodman/kmods/mods/artists/Necros/Original_Names/

Not only are there tracks there that haven't yet been included in this web shrine, but they have the original file names! These will slowly be integrated here, but they will be uploaded as new attachments so the old links continue to work. Also, in order to listen to tracks sent by Shane, I installed ModPlug and found it runs great under WINE in Lubuntu. I took the opportunity to convert those and a couple more songs into MP3's.
