MGSV: How to add "Duran Duran - Invisible" to your game

First, you'll need the song MP3 file. If you already have it, great! If you don't, it's pretty simple:

I'll put this link that sends you to the auto-generated audio version, just in case you're too lazy to open the browser and search for it yourself:

Then, just use your favorite site/tool to download it directly as a MP3 file. Most of them will ask you for the URL, but I assume you know how to use it.

Once you have the song's file, just go to the game's folder (you can do it by right-clicking the game's name on your Steam Library and then clicking on "Browse local files" in the "Manage" subentry).

There, you'll find a folder named "CustomSoundtrack", and now it's quite obvious what you have to do.

Just copy (or cut) the song's MP3 file from where you saved it and then paste it in the folder. It'll already have a song called "Sands" inside it, so you'll probably end up with the folder looking like mine in the image

Enjoy!
