Custom music for menus in TDU Platinum

[The burner of rubber]

So, I'm just curious: how can I program my own menu music into TDU Platinum?

I already know how to program music for the radio, but how can I do it for the menus (house, boutique, garage...)

How about actually making MP3 files the music you hear in the menus? How do you do that?

I assume replacing the files. I don't know exactly never did that. Also TDU uses WAV not MP3 except user music
