Recently I've tried experimenting with the tracks folder in Marathon 1, using my copy of Redux. I replaced the default Redux tracks with the CD enhanced versions, Eupfhoria tracks (for the ones that Alex missed for the sake of his 7 reference) and my Siege of Lh'owon mashup for Rapture, keeping the Eupfhoria Rapture too just in case.
I made sure to back up the original tracks in case I go back to them later. The reason for my amateur music mod being that I feel Craig's tracks fit Eternal X more than they do Marathon 1, as things have gotten more serious by Eternal and the music helps convey that.
If anyone would like to try the game with those tracks, I've included a link to it here: https://drive.google.com/file/d/1b5Rot_n8FtpWErvGeRyPWzSXBchy68e_/view?usp=sharing
Theoretically, it should be possible to use them in vanilla Marathon 1 or M1A1 too, or instead of using them in Redux if the files are renamed accordingly.
Credit goes to Alexander Seropian for the CD tracks, Zuranthus for the Eupfhoria tracks, and Marty O'Donnell, Kevin Kliesch and Craig Hardgrove for the ones I used to make Siege of Lh'owon.
