I got tired of waiting for one so I made it myself.
This is the first mod I've ever made and I gotta say that adding music to CustomOST isnt impressive but for those who are too intimidated or just too lazy to try it themselves (like I was) here it is.
I would like to have any feedback possible since this is my first mod ever and I am rather new to this.
Please do suggest what other music I should add to Payday 2, preferably from the Final Fantasy franchice since it is severly lacking in Payday 2 mods.

This mod of course requires Custom OST.

Put the files in to "CustomOSTTracks" folder.
