Hi, I'm making a music mod and I have one question:
How do I override core game stuff? Like if I want to change the menu song, how would I stop the other one from playing without getting a ton of "Missing Song_Entry def" error messages on launch?
Also how would I stop the base game music from playing and instead replace with my own music?
Thanks, also I'm completely new to modding and only know the very basics of RM modding, so keep it simple

So, this is entirely theoretical, but as I'm working on my Halo music mods and planning a "Halo Overhaul" to the game, I had a thought.
Could you change the red planet background of the title screen, or is that not possible/extremely complicated? I'd love to change it to a Halo ring for a Halo themed playthrough.
If it is possible, can anyone explain how it could be done?

Hi!
I posted this on Reddit before, and was directed here, so I made an account just to ask
I'd like to add some music to the game (Specifically the Halo 3 ODST soundtrack, and maybe other Halo games) for my own personal enjoyment, then also upload them as mods.
I've looked into it a bit and downloaded an XML code editor and found the SongDef files in Rimworld's Core folder, although I'm completely lost as to how I should go about inserting new songs.
Any help is greatly appreciated, thanks in advance
