We like to switch up what you may hear in the main menu. It's not necessarily what you will hear in the trailer.
I wonder since when did it become so? Previously, the trailer and the game used the same tracks, except that they were remounted for certain moments. Grim Treatments' Asylum track was cool. The track Asylum from Grim Treatments was cool but Pumpkinhead from Infernal Insurrection is a hassle where you can only hear the beginning of something interesting at the end. But this does not happen instead of Doom at the minimum salaries, I hear the terrible sounds of "Hell" on the new one. Likewise with Christmas Crackdown, the track from the Yuletide Horror update is cool and the CC sucks and it's problematic due to the fact that it seems to be cut off, it's absolutely not cool. It's not KF2 style, with cool music in every update. Or do we still have to pay extra for the DLC version of the tracks? If such tracks are available until the end of the game's support, then it's terrible. If you no longer want to try, why not make a button in the Sound option, for example, as in PAYDAY 2 where you can yourself and it will just be convenient. I hate the Monstocity track and every time I have to manually change the files on Pandemic.
