The music comes from the Payday co-op heist games by Overkill Software, most widely known from Payday 2 released in 2013, with music composed by Simon Viklund. The soundtrack uses a dynamic system that shifts between stealth, control and assault phases, with the assault layer bringing in the full beat when police attack in waves. Clips of that phase spread through gameplay videos, memes and edits because the change is so recognisable, and creators still reuse the loop whenever a scene needs instant heist pressure.
