Music modification

Hello, I got a question for the music on dbd...I wanted to replace them in my game but I need the code in UE4 for it right ? to modify the queue of each music, does anyone know how to pass or crack it ? I'm kind of struggling to replace different music on each killer, it's almost a cheat but not really ?

If I'm wrong does anyone know how to help me with that ? (if anyone tried that of course)
(English isn't my first languages if you got problems to understand me just ask.)

Any modification games files=cheats, and chance on ban. U need unpack pak files (dont remember which) but in him u can find game sounds.

I actually found them but i think in the source code there is like a queue of music. I know some killers have different music but most of them have different one and i wanna change them for each one, like nurse, trapper ect...You think you know a way without changing one who will change the others ?
