She is almost impossible to understand.

So because she is so incredibly hard to understand I'll write out the steps here.

Open your SongDatabase.xml located in:

AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios\Config

Add into the file:

<li>
<SongDef>Name of Song</SongDef>
<Seasons>
<li>Undefined</li>
</Seasons>
</li>

This makes the song only play in that set season, which since we set it to undefined means it never plays.

Do that for all the songs you don't want.

thanks
