To upload your own files:
1. go to the music file, shift right click, "copy path".
2. press windows key and R, type %appdata%
3. Go to the root folder of %appdata% and go to AppData\Local\BusSimulator18\Saved\Config\WindowsNoEditor and open "Game"
4. Find "UserDefinedStreamingPlaylist". After the =, type "file://" and then paste the music file's path on the drive, BEFORE the ". For example... UserDefinedStreamingPlaylist="file://D:/example.mp4"

for every seperate file, you will have to make a new UserDefinedStreaminingPlaylist line. So, to add an additional song, you would create a new line after UserDefinedStreamingPlaylist="file://D:/example.mp4" and put UserDefinedStreamingPlaylist="file://(path of second song)".

Adding radio stations
https://streamurl.link has tons of radios, but if someone is popular enough you can maybe find an indepedent radio stream dedicated to just them. It works the same way, just paste the link to the stream right after. Example UserDefinedStreamingPlaylist="stream-150.zeno.fm/d0pnqeqv1f9uv?zs=ibehgYKYT6OAR-hurWcUyQ"


Make sure
1. Every seperate file/radio station is on it's own line.
2. Every file is .mp4. x264 mp4 is the most universally compatible file type in unreal
3. When converting audio to mp4, songs may multiply in file size if you don't want them to sound compressed
4. Make sure your .mp4 has no video. On converteasy website, select "copy" for both audio and video, as far as I can tell this is lossless quality but the filesizes can get ridiculous.

To preview if your music works, go to the audio settings and use the test they give you. You should hear your music start to play after a few seconds.

The radio can be in awkward places depending on the bus



In any bus, you can just use the action menu to use the radio and skip songs.
