Okay so I got my traxxx uploaded.
Here is what you do -
1.
Download the "pure" RACE mod (huh, I wonder if they noticed how that sounds)
2. Extract it to your FO:NV folder. In Data/Sounds/Songs/RACE/ there there will be 250 .mp3 files. All of them are about a second long and consist of a metronome sound. If you want to, you can copy your music into this folder and rename the songs as "01", "02","03" etc. and you will be able to select said songs (or utilize a random selector) through a weightless quest item in the Apparel section of your inventory. Optimally, songs should be at 192 kbps maximum, lest you cause memory problems. You don't have to fill all 250 slots - You can set limits on what the game uses by factors of 10 through the inventory item.
3. Make sure to check the .esp in the Data Files section of the launcher, and it should work.
Now, if you want to use my meticulously curated bloc of 120 songs, you can get them here, broken up into 4 parts -
Part 1,
Part 2,
Part 3, and
Part 4. If you only want to use one or a few of them, each .rar includes a segment of the whole (part 1= 1-75, part 2= 76-125, etc.) Included are Mark Morgan's remastered FO soundtracks, and Aphex Twin's
Selected Ambient Works Vol. 2, which Morgan blatantly stole from wholesale in some cases and took general cues from in others. There's also quite a bit of stuff from Nest, Caul, Casino Vs. Japan, Keith Fullerton Whitman, Coil, and others. Requirements were that they had to be instrumental and somewhat desolate in sound.
If you use my tracks and run into any problems, let me know. RACE isn't entirely stable - it won't crash your game but it might "skip" to an earlier point in a song, or stutter when moving between areas. It shouldn't be anything too severe.
