Tired of the hard things try this.

I don't really know if this is worth posting but well it's just something that's really easy to do. You can easily delete the music when you start Combat Arms or when your in a waiting room. SAY your to lazy to go to in options and turn them down well do this. *on your computer* Go to start ,run and search C:/Nexon/Combat Arms/Game/BGM. When your in there that will be the 2 sounds for when starting Combat Arms and when your in the waiting room. You can just remove them from the folder and put them some where else or just delete them. - Just wanted to post something simple.
[Any idiot can do this].

Oooh, could you possibly put in other music that will automatically play in place of the default sounds?

Already posted it not too long ago. Works, and is kind of fun to try.
