How to replace preface.ogg that will actually work?

[GunNut]

I've replaced newmusic.bank, oldmusic.bank, i've replaced preface.ogg with my own preface.ogg, i've replaced sounds_music script, nothing works, the old preface.ogg still play. The only way i can "replace" the music is by deleting the file alltogether, but that's not what i want obviously. Is there any way to change that particular music? Music mods from steam workshop work fine, but the original preface.ogg STILL play, every other piece of music is replaced, so i have no idea WHAT IS GOING ON?
