This mod adds all variants as one heist track, basically every Going POSTAL track is a separate alt assault track, this means that it will rotates through each track while in a assault, you probably won't end up hearing every variant because the assault usually takes up to 2-3 minutes.
In my experience, I didn't had any issue with the memory RAM while using it with 14 heist track mods while the optimized loading music is disabled. Also, I'm not responsible for any crash or damage (to your brain). wink wink.
