Re: Sims 3 Can i turn off game music but keep stereo music on?

@ChipWasntHere  You do need to either use a mod or tweak some game files yourself.  I can't link anything directly, but this discussion provides the information you need.

I did search the Sims Asylum, where Twoftmama hosts her work, and didn't find what you're looking for, just a set of mods to mute in-game sounds from professions like Ghost Hunter and the ones from Showtime.  But you could ask there too.  You do need to be signed in to see anything on that site.
