Replacing a type of music

I already know how to make my own menu music for TDU Platinum,

but what if I would like to change the music to the pre-race menu, where you can change your car before you begin and stuff like that? 

It's probably under Euro in the game's folder, but what's it called?

Euro/Bnk/Sound/Musics

What's the pre-race music audio file called?

no idea, never bothered to replace it
