For some reason, it seemed like an abnormal amount of people were having issues, so I'm going into a more detailed guide here of every step of the process:
Start by going to the download page on Nexus Mods
This mod is set to just replace the music on the Canyon map
If you bought the game through steam, you can right click on the "Blade & Sorcery" title, click on properties, local files, then "Browse Local Files"
The default install location should be
C:\\Program Files (x86)\\Steam\\steamapps\\common\\Blade & Sorcery
