Yes, yes, I know you can mute the in-game music and leave Steam's music player or somesuch running in the background. I want the music controlled by the game's systems (i.e. switching tracks between races and menus, etc).
I've extracted the Audio-music.zad and edited the xml and playlist.cfg files to add the songs of my choosing, and have replaced/renamed the default tracks with songs of my choosing, but the game doesn't load. It sits there at the splash screen. I've verified the game cache through Steam, I've renamed my custom archive to zAudio-music.zad.
How do I get this to work?
