Found Out How to Set up Custom Radio / Songs

[Vult]

Steps:

1) Find the link to a song or playlist (from a certain Green-Black-logo music player app that shall not be named).

2) Paste link to spotidownloader (or an equivalent site) to download song(s).

3) Download zip file from site.

4) Extract zip file somewhere onto PC (Use Winrar or equivalent to extract files). You should now have a folder filled with your songs in .mp3 format.

5) Copy (or cut) all songs from the aforementioned folder.

6) Paste .mp3 files directly into: %localappdata%/PenDriverPro/Custom/Radio/
Note: You can paste "%localappdata%/PenDriverPro/Custom/Radio/" directly into your File Explorer search bar to get to this folder location faster.

7) You're done. Now start up the game and change your Music Source Radio setting to either "Default and Custom" or "Custom"

More notes:
1) Developers mention that ".wav, .mp3, and .ogg files, as well as simple .m3u/.m3u8 files" are supported.
2) For more info, scroll down to the section titled "Play Custom Music from Local Storage (PC ONLY)" at:
