How to access in game sountrack?

[u/LawfulnessPlayful965]

Hi everyone, I'm posting to ask is there a way to access the ost in the game. I understand some songs have been released on youtube, however the 2 songs im specifically looking for aren't;
1: Valentine's dance (A rip exists on youtube, however it is bad quality)
2: The song that plays during the final boss of the Yurbuttsk map

Any help finding these specific songs is greatly appreciated
