I made this because I saw someone do something similar but it didn't work....so this one does ^-^ just changes the menu/loading music.

I do NOT own the rights to the song

To install:

1. Start OpenIV
2. Extract "trap loading.zip" on your desktop
3. Enable Edit Mode in OpenIV
4. Go to (mods)/x64/audio/sfx/PROLOGUE.rpf
5. Replace the td_loading_music.awc

You're done! Enjoy. ^-^
