Disabling the 'in-game' mood music?

[Snacko]

Is there any way to disable the 'in-game' mood music, 'other than' turning the music down or off in the Sound/Options?

When you turn the Music down or off in the Sound/Options, it also turns down or off your Gramaphone and Radio. I want these, but don't like that mood music the game plays by default. So, I have to turn the Music off in the Sound/Options. Then every time I want to listen to the Radio or Gramaphone I have to go and turn the Music on again, and then off again in the Sound Options.

I tried hacking some of the files, but then the game started crashing, so I guess I did something wrong....
