This is fixed in the shopping spree update, you no longer need this
fixes the stealth music not changing in delivery charge
This is not fully fixable, because the heist itself doesnt know when to change the intensity, so what i did is make it change by time instead of the objectives changing the intensities (the heist doesnt have objectives that change the intensities).
(stealth 1, 2, 3 will play once, then stealth 4 loops twice, and after that stealth 5 loops infinitely.
