This mod adds a heist custom track This I Know to the game, which includes:
zYnthetic - Bone Shards for a Stealth phase
zYnthetic - Rendezvous Point for a Control and an Anticipation phases
Demon Hunter - This I Know (instrumental with vocal at the end) for an Assault phase

I've tried to recreate a true KF2 music exprerience as much as it possible to do in PD2 by putting two "ambient" tracks (which are playing before and between the waves) - stealth one is more calm, control one is a bit more tense. Also I didn't cut the introduction of an assault track and put it all in an assault-entry part (not in the main loop), cuz this is how you hear it in KF2 when a wave begins.
And yea, I know there is a huge music pack with a majority of KF2 OSTs, but man this mod is just a piece of shit's shit, so I had to made mine.

To install you first of all need BLT + BeardLib + BeardLib Music Module Addon. Then insert the "This I Know" folder in your "PAYDAY 2/assets/mod_overrides/" and you're done.

Wanna listen how the track sounds in the game? Here is a gameplay video (wasn't able to demonstrate the assault loop, sry):
