Hey, is there any way to replace Automations background music with my own?
Yes! Turn the in-game music volume down to 0, play your own in the background. In the game though, I don’t think so, although if you can find the music files in the installation folder (dubious) and they are in a “normal” file format (even more dubious) you could try swapping them with your music, renamed to fit the names of those files.
But, TBH, music in Automation has basically no reason to dynamically change, so IMO my half-joke method from the start is sufficient, I use it myself.
While I do the first one all the time, I just wanna make my own custom one with a handful of tracks layered over garage noise to give me a Forza Horizon 2 vibe
