(Experimental version)
Did what I could polishing each file in Police Station, but after hotfix update game randomizes the volume, pitch and speed, so modded tracks may sound quite goofy for quite a while until I figure out more robust solution.

(Recommended version)
Added a few tracks for police station, fixed some volume issues

Replaces only Main Menu music with main themes from Rainbow Six, Ghost Recon and Splinter Cell

Replaces only the tracks from Police Station.

Still work-in-progress, despite my polishing works(game is actively refusing to have non-native music)

Splash screen on game start-up is slightly changed...
