Alright ramblers, let's get rambling.

This BeardLib heist track brings an unused song found in the game files, named Insane. It was (presumably) made by Simon Viklund.

Includes every single portion (Stealth (taken from Full Force Forward), Control, Anticipation, Assault)

Song file gotten from The Cutting Room Floor.
