So, I added The Living Tombstone's "It's been so long" and "FNAF 1" theme to PAYDAY 2
Although, I'm sad to say that I couldn't find a section of either song to fit and loop for stealth, so I took my chance to add Kevin Macleod's "Sneaky Snitch" in stealth's section.
A very fitting choice, I know. I hope you enjoy this, I will be uploading the other songs I added to this marvelous game later.
I will add a link to my youtube video showing the song play during a heist.
