INSTALLATION: Pick whatever song you wish to have and place the .AWC in "mods/update/x64/dlcpacks/mpvinewood/dlc.rpf/x64/audio/sfx/dlc_vinewood"

After that, load in the game and teleport to the Diamond Casino (normal version not heist one) via a trainer (Simple Trainer for example)

The restroom is near the poker tables, just head in and you'll hear the new song you picked, enjoy!

Anyways, hope you enjoy this random mod I thought of! -EcLiPsE-
