In-game music mod - small problem

Hello there.
So, I've got a small problem with my own music mod. After replacing it, at the beginning of certain parts of soundtrack (ex. assault) I can hear some really short parts of original, not replaced song. In this case - it is Pimped Out Getaway.
Preview of my problem:
Just drop it to mod_overrides folder.

This isn't hard at all, believe me. At first it seems like it is, but after you tried it - it's like riding a bicycle.
And the Steam guide is pretty straight-forward, too. I hadn't troubles with it.
Edit: I actually thought your mod had some scripting to it, but after looking at it, it doesn't seem to be the case.
It'll definitely take longer to learn if you've never done the scripting, so guess your choice not to try it is justified. Your call, but I'd suggest you give it a try.
