Are you looking to spice up Luna Nights gameplay? Here's how to change TLN's BGM to any song.
 

Finding the Files For the OST

1. Right-click on Touhou Luna Nights and click Manage. Next, click "Browse local data".
 
 

 
 
2. Open the data directory and all music/misc files should be found in.ogg format.
 
 

 
 

 
 
 

How to replace your music.

Next step: Get music file(,) which will replace a track in the OST. You can download it in a.ogg format, or convert an.mp3/wav/whatever.

 
 
Youtube is the easiest place to search for any song, (using Transformations From TWEWY.
 
 

 
 
Now, you will need to search for a YT Link Converter. I personally use YT5S, however any converter will do. Copy the video link and then click "Start".
 
 

 
 
YT5S allows you to download the song as a.ogg.
 
 

 
 
You need to convert a file format from another than.ogg to be able to download the song.
 
 
 

Getting the Music to Work In-Game

Now that your.ogg-format song is complete, you can go back to the data directory
 
 

 
 
Once the song is found, you will need the correct theme to replace. Here's a breakdown in case you are confused
